It's probably me but I just don't get Poser 10's lights. Yes, I know I've posted before about upgrading to 11/12 but sometimes it's just not an option. Anyway, I've got a floor, a table, a lamp and a sofa. The walls have a wallpaper texture on them. I'm trying to do two things. Make the lamp look like it's on and make the room look like its softly lit. Trouble is what I see in the preview window doesn't match what renders out. Also if I use a spotlight I get a hard edge when it renders. I've gone through the Poser manual but its not much help. I've sort of got the effect I want by using a point light near the lamp then a spot light pointing at the lampshade but it's not really good enough. Are Poser's lights really poor or is it as I suspect that I'm just not very good at it after all.

A spotlight gives a haard edge when used. Look at the Bat signal. Spotlight. You want to use a pointlight, but you need to control the brightness intensity. A pointlight will act like a lightbulb and shine in a 360 degree circle. Just like a real lightbulb would.

Yes, I've got the idea of using a point light to light the actual scene but I can't get the lampshade to glow like a real one does. That's why I thought of pointing a spotlight at it. The lampshade properties say its a light emitter but checking or unchecking it doesn't seem to make a difference to my render. I have watched the Renderosity P10/Pro video tutorials on lighting and render settings and although they're really good and have helped in other ways they're not really helping me with this particular issue. It must be my lack of ability because I'm having the same problems with a campfire scene. hey ho, at least my daylight scenes work fine!

Make angle_start and angle_end different by a suitamle amount. It makes the edges of the lightspot less sharp. Sharpness of shadows is via the blur radius setting of the light.

to let the lampshade shine use the ambient channel for the light to be emitted and render with indirect light settings on.

The real approach is to make the lampshade translucent so the pointlight within is allowed to shine through the mesh.

Crank up the ambient value on your bulb

Make the lampshade slightly transparent; here I used a desaturated version of the lampshade's diffuse texture and plugged it into the transparency of the the shade material as a trans map.

Position a low intensity point light where the lamps bulb is.

Render with IDL

(forgive the crappy render but the only one I have using above method, figure is Glidman's free NoName Doll)

I have to agree with hborre, make the lampshade translucent, not transparent.

So just to see what I'm talking about. I pulled out Poser 2014 and started it up. Loaded the table and lamp. There is a point light loaded where the bulb is in the lamp. Note you can see the shadow of the lamp on the table. I also turned off all other lights in the scene. Just the point light is turned on in this scene. Also, you will be controlling translucense through the shade, not the light.

I'm sorry but that's not the effect I'm trying to get. This is the sort of thing I'm trying to do;-

Hi, the comment I've just posted was about the image with the girl in it. The one with the table is closer to what I'm trying to achieve.

Setting your light to an inverse square attenuation will cause the emission to fall off with distance. In those photographic examples, the intensity needs to be cranked up high.

I took a closer look at trying to emulate the lighting in the photographs and this is what I came up with rendering in Firefly.

Firefly light.jpg

Three things you need to pay attention to when setting up your scene. One, always have something to reflect your light around the scene, may it be a skydome or interior walls. You need the necessary illumination bounces to properly light the area. Two, set your light to inverse square, you need as realistic a fall off as possible so everything looks right. Setting an ambiance on the light shade, for example, looks wrong and artificial. You can't control inverse square properly. Three, turn on ambient occlusion on your light and adjust your Shadow Blur Radius to soften shadow sharpness along the edges. In some cases, you may need to introduce a Diffuse IBL to help fill in exceptionally deep shadows.

I might also add, object materials could use tweaking or a complete overhaul to help get the effects you're looking for.

Doesn't look much different than mine. Shrug. Lol.

The difference is my render has only one light source, your's has additional lighting in the scene. If you re-render with the intensity of the second light reduced, the scene would look a little more realistic. A fill light casting no shadows would round out the scene. But to each it's own. Whatever makes you happy.

I haven't worked on lampshades for a while, but I found these two examples:

Poser 10 and 2014 don't have Superfly.

HMM, the Superfly renders do look good. Trouble is I only ever have limited time on my PC and I do like to spend it with Poser and Vue. I'll need to get a lot better at lighting in general I think before I go for P11/12. Hey ho, at least I'm learning stuff even at my age! I hope the guy on the seat hasn't been waiting long...


  piersyf    ( ) ( posted at 6:28PM Sun, 27 September 2020  · @4400467

Go here, download and read. It's not entirely correct, but close enough. Then decide on using Superfly. Frankly, materials are a ton easier in Superfly as well.

The guy on the seat is probably waiting for his Superfly render to finish. ;-)

Superfly does look more realistic, but man is it slow. I'm really hoping Poser 12 will speed things up a bit.


  EClark1894    ( ) ( posted at 7:20PM Sun, 27 September 2020  · @4400470

I have posted on articles you can read to speed Superfly and Cycles up a bit. I may even still have those links if they're still up.
