I’ve got an odd one here. I have a wood-burning stove/fireplace inside a home. Inside the fireplace each wall has a burning wood material applied to it. From the outside of the fireplace it appears to be brighter inside with the fire burning.
When I apply an Environment and update the outside of the fireplace with PBR materials it looks great. Unfortunately the fire burning inside is now affected by environmental lighting and goes dark, since there is no environmental light inside. When I turn environments off the fire gets brighter inside.
Is there any way of having a material NOT be affected by environmental light? This way the brighter material would remain so inside the fireplace.
As it stands I believe that environment lighting isn’t blocked by walls, and things inside are affect just as much as if there were no walls. There also isn’t a way to control the amount of reflection at a material level.
What francisquitof suggested might work around the problem.
Unforunately not, SketchUp doesn’t currently offer any lighting functionality, when you turn on “photorealistic materials” everything is less bright than something illuminated.
Your best best would be to rotate the environment until you get a spot where the fire textures are being directly “lit”, you could then play around with the exposure too.
SketchUp doesn’t support any whiter than white materials, so you have to think about your model as if you are painting.
If you need your fire texture to look brighter, then you’ll need to make eveything else darker to provide the contrast required.
