Quote - The missing wall is not a problem (leak) if you're modeling the lighting of a real outdoor seating area (think porch). In that case, the sky and environment will contribute far more than the missing wall would be contributing. The missing wall is a net addition when the env sphere is bright.

Re glowing couch back against wall - IDL reflection is wrong in Poser. Use D3D dialog to decrease IDL intensity to .65.

^^ This.

Smith Micro developers don't even use their own product or else they would of set the default IDL lower.  Hopefully poser ends up in the hands of a competent company in the future.

the trouble here is over the

couchs

 

I played with all the possible combinations, but the problem does not disappear.

that's why I asked you and to BB the settings for BB's dome and sun light.

I think the problem comes from external light

this is the render

I have made a test with M4, the same problem is over the M4 skin, but this is a future step.

 

1. Use one directional light with IDL at 6.

2. Add BB's EnvSphere.

3. Try another couch to see if the same problem exists, or any other object where two planes meet at 90 degrees.

4. Simplify the textures on the couch as much as possible.

5. Set the irradiance cach for IDL higher (70 or higher) and the irradiance caching for raytracing to 100.
