Different lights

Post by ElGreco » Sun Apr 14, 2013 5:05 am

Hey Community,

I hope I'm right here, I have a question to light materials.
First of all I already had problems to figure out how lighting works in Indigo, but ok this is another topic :D
My question is, I have two different light materials, which I want to set to two different UV - Spheres,
but the problem is that only one material is active. I mean I have in Blender material1 and material2 with the indigo light material1 and mat2 on them ( 1-1, 2-2 ) but only light material 1 or 2 shows up, never both.

What am I doing wrong?

Sincerly,
ElGreco

Post a screenshot of both material settings, tonemapping settings, and maybe we can help you out.

There is one very classical error : maybe both sources are active, but one is much more powerful than the other one. If you are using Reinhard tonemapping, the auto exposure will adapt more or less to the brightest source, making the faintest one not lighting the scene enough to be noticeable. You need to change tonemapping to another one (linear for instance) and check the power of light sources.

Thx for the answers,

but problem still exists. I dont have a knowledge of Tone Mapping, but the color doesnt change.
So I made some screen shots.

Material1:

Material2:

As I said I'm not used to the lighting.
Hope you can help me.

1. Turn your exposure down when using Linear, preferably use Camera tonemapping and expose it properly.
2. Show a screenshot of your settings in Blender.
3. Both light materials seem to be named 'Material' from what I can see. If that's the case, it's probably a naming conflict. Try setting up the materials from Blender so you can be sure that they're distinct.
4. Make sure you're not using instances of the light object (the sphere), make sure they both have unique meshes.
