Subject: P5 Ray-Trace Reflection Bug Report for CL

As you can see by the attatched image, there is a problem when rendering transparent/semi-transparent object reflections. Apparently, when the ray-tracer runs into an object that has some transparency, it simply substitutes the background color instead of the objects behind the transparent item. Note that this is not limited to transmapped items... the fingernails have no transmap, but do have some transparency dialed in. Is this one of the items being worked on in the first patch? BTW, this happens in both draft and production modes (this image is production mode) and I've tried all different kinds of material settings... if there is some work-around or correct settings you can show me, that would be great. Thanks, - Keith

thats looking weird, and was not what i ecpected from the new ff render.wanted to stop from exporting poser to bryce

On the plus side, the bug only occurs with transparency in reflections, and only with gradient values. A transparency value of 0 (completely opaque) or 1 (completely transparent) still reflects properly, although that isn't much of a consolation.



aleks ( ) posted Sun, 22 September 2002 at 2:21 AM

there was some similar bug long time ago in some 3d-software i don't remember name any more, and the solution was to increase the light bounce number in the raytracing properties. since i don't have p5 yet, i can't say if this is possible at all with the glowingmoth, but it's worth giving it a try.


Spanki ( ) posted Sun, 22 September 2002 at 2:41 AM

In the above image, I had increased th bounces from 4 to 8 - I could try more, but it really should be caught on the first bounce, so I'm not too hopeful that that would help. Thanks for the suggestion though.

yep, you're right, that should be enough... well... p5 is cheap... ;]P


ronmolina ( ) posted Sun, 22 September 2002 at 9:36 AM

I am getting the same results. I thought I had it figured out but I dont think so. Also the new hair does not appear in my reflections. I am going to spend some time today playing with the various settings. Could even be a lighting setting. Who knows. Ron


aleks ( ) posted Sun, 22 September 2002 at 10:13 AM

funny thought: try to put something behind the mirror where reflections of transparency are. maybe the renderer thinks that reflected transparency is in fact part of the object that's reflecting ;)


herr67 ( ) posted Sun, 22 September 2002 at 10:24 AM

If you play with the translucence color of the transparent items you get better results but it is still is not a fix nor a proper work around.


ronmolina ( ) posted Sun, 22 September 2002 at 10:39 AM

I have been playing with every thing I can think of this morning. Still trying different settings. I tried translucence. I havent given up yet. Ron


Spanki ( ) posted Sun, 22 September 2002 at 2:41 PM

D'oh! I hadn't tried the new hair yet - thanks for the update. I've been trying some things as well (plugging a reflection node into the transparency/translucncy channels of the mirror node, etc.) but hadn't found any work-arounds yet.

Little_Dragon ( ) posted Sun, 22 September 2002 at 7:38 PM

I played around with the Material Room and render settings for sixteen hours, and have reached the conclusion that it's the way the renderer handles (or doesn't handle) transparency gradients. I've reduced transmaps to two colours (pure black and pure white, no grey), and the reflection renders properly. It's the in-between shades of grey that cause problems.



ronmolina ( ) posted Sun, 22 September 2002 at 7:47 PM

I played all day today and did get the new hair to work in reflections. I was getting nothing or the background color before. Tomorrow its trans hair. LD what are you setting as the value for transparency? Ron


Little_Dragon ( ) posted Sun, 22 September 2002 at 11:47 PM

I usually leave it at 1.0 when I plug in a transmap, but have tried other values. Let us know if you succeed.



PabloS ( ) posted Tue, 24 September 2002 at 6:22 PM

Boy! I hope this is one of the fixes we see in the Sep 30 P5 patch.

Well I did better with the mirror and transparent then spanki, but I'm having a hell of a time with the dynamic hair reflecting. If I try checking the "Visible in Ray-Tracing" in the hair properties and try to render. Poser 5 stops responding. :(

Settings for a trans map.


Spanki ( ) posted Tue, 24 September 2002 at 10:50 PM

Sirkrite... I hate to be the bearer of bad news, but.. you got the same results that I did ;). I made the background a bright color on purpose, so that it would show up better... if you change your bakground to hot-pink, it'll show the problem (righ now, the bleed-through is just gray, so it blends in).

Actually.. I'm not sure what I just said is true.. but I'd be interested to see an image with a hot-pink background, just to be sure.

Tried, tried again but no luck. :( They will have to fix the Ray-Tracer so it looks through transparent objects and see what is behind it. Instead of it seeing a transparent object and interrupting it as the reflected area is transparent also. As far as the dynamic hair... Looks like a big problem! It has no UVs to bounce the rays off of. : It's Vampire hair! Found a cheat fix for the mirror, place a square behind it and set the color to what youre trying to reflex.


aleks ( ) posted Wed, 25 September 2002 at 10:20 AM

thought so (see post #8). reflecting object just takes the trasparency information when reflecting as if it was it's own material. my nasty suspicion is that it isn't really reflecting with bouncing lights, but it renders a fake from the "other side" and then map it on... so it makes me wonder: how did kupa produced that reflection image - i think it was at rdna - does anybody have it still?


sirkrite ( ) posted Wed, 25 September 2002 at 10:33 AM

I don't think so, if it was rendering a fake from the other side, the trasparents would still work and you would see the dynamic hair in the mirror. (Look at post 21)


sirkrite ( ) posted Wed, 25 September 2002 at 10:37 AM

The pink your seeing on the head is the scull cap not the hair. The hair is invisible not transparent.


aleks ( ) posted Wed, 25 September 2002 at 10:41 AM

hmmm... can you make another mirror behind her, so that we can see that reflection also in the first mirror? :)

Take a look! :)


Spanki ( ) posted Wed, 25 September 2002 at 1:03 PM

Hmmm.. I noted at the time that reflections of reflections didn't work correctly, but now you've got me curious to see that image he made again (it seems to me that there WAS dynamic hair in that image)... off to search, back in a bit with the link...

Ok, something's fishy.. I found the original post (see link, scroll down to post #31). His image is definately showing dynamic hair. I wish he (or someone from CL) would pop in here and show us the settings used to achieve that, since no one who's bought the product has been able to reproduce it. Maybe he was (already) using the 'patched' version ? ;).

aleks ( ) posted Wed, 25 September 2002 at 2:07 PM

yeah, i still think it was a fake. if you look at it closely, you'll notice several things: - she is not only mirrored, but inverted. her left shoulder is slightly higher left then in the mirror. in the mirror it's vice versa. - her right ear isn't covered with hair. in the mirror it'S covered to the half. - the reflection on the big ball in the mirror isn't possible that way. the image should be way smaller then the real ball infront of her. - her reflection on the ball has no hair. yet it's fully there in the mirror. to me this is a serious manipulation that borders almost to a ehm... let's not say it...


shadownet ( ) posted Wed, 25 September 2002 at 2:15 PM

Wouldn't it be nice if the manual the came with the software explained this stuff? Or is it just silly ol me expecting too much!


sirkrite ( ) posted Wed, 25 September 2002 at 4:30 PM

I got another one for you. Did you know that if you enlarge the square to the size of say a wall, it would not cast reflections anymore? So let's say we want to have a figure standing in a lake or a pool, it most likely wont have reflections. There is definitely something wrong with Kupa's picture.


sirkrite ( ) posted Wed, 25 September 2002 at 4:40 PM

Okay Spanki, How did you get a wall to Reflect? Every time I try to enlarge the square that large, it won't reflect anything.


Spanki ( ) posted Wed, 25 September 2002 at 5:39 PM

I think the problem is in the scaling.. it scales the reflection up as well (so far that you don't recognise it as a reflection). I still hadn't tried this, but you might be able to scale the prop up, then export the .obj and re-import it.. this will reset the scale values to 100% and that might fix it. The 'walls' I used were part of a room prop... they were already scaled to that size.

Okay, I've been racking my brains here. Cannot get the dynamic hair to render using a square as a mirror, it just keeps stopping and not responding. But! I was able to get it to render using the ball and the settings CL has on their site. I have a feeling it's a memory issue. I have 512 of SDRam and when I check, it's maxing it out! This shouldn't be happening with a simple picture like this.


ronmolina ( ) posted Wed, 25 September 2002 at 10:55 PM

I have 512 and it does not max out here. Ron
