Is it possible in poser 6 to have an effect like in this photo where the light shining trhough the bottle causes the counter to look green? If it is how would you do it? (even if it's not a trick with the lights)

there is a cheat where you set the shadow color to the color you want.

I dont know what poser does with transmitted light in raytrace. You might look up caustics

it looks like caustics to me. use some renderer other than poser for that. not maxwell, though. it's even slower than poser IMVHO. there is a trick to fake caustics in P6 (and maybe P5), but I believe it applies to light materials and underwater scenes, and not to bottles nor diamonds nor any actual refractive nor reflective properties of the objects themselves.

This is a question for Bagginsbill. He'd know.

There is no automatic way. Reflections and refractions are only calculated for rays of light which tracked backward from the camera through explicit bending due to direct reflection and refraction. Poser doesn't do those focused bits of light transmitted through curved transparent surfaces that are then diffusely reflected by other surfaces, i.e. caustics. However, you can fake them.

Many people don't know there are some crazy things you can do with the material room on a light. Here I've created a spotlight and attached an image to it in the material room. You can point this light anywhere you want to simulate caustics. You can draw any pattern in an image and attach it (like a light gel) to the light. The light behaves as if the image is being held in front of the bulb - whatever is in the image colors or darkens the light coming from the bulb and is projected onto other surfaces.


Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)

Here's a screenshot of the posing setup with the spotlight. Turn shadows off for this light.

Man bagginsbill that has to win an award to the simplest Material Room trick you have ever posted!  LOL.

Seriously, though, thanks for that.  I've used the Material Room on a light to set up shadows, like from verticle blinds, but this handy little idea completely escaped me.  Thanks!

Thanks! That is cool!
