emission alpha

10 years ago • updated by 10 years ago • 5

Hi, I have created a caustic shader which I use with the Unity Projector. It is and alpha shader which only projects the caustics on a mesh.The problem I have is that when I put the Light Mode to unlit I can't get the emission past 1(And that is not light enough), while when I switch the Light Mode to Blinn the emission can be set to what ever I want.

What did you expect to happen, and what happened instead?

I expect when I pump up the emission the caustics will get brighter, instead the emission can't get past 1, every higher value doesn't do a thing. This works fine with the shader set to Blinn-Phong mode but I thought performance wise the effect would be better in Unlit Mode. But than the emission doesn't work the same.

I can't seem to replicate this, works fine for me. Got a step by step on how to reproduce this form scratch?

Now you got to connect the Blue channel in the Alpha slot and than it won't get brighter than 1. (If your texture has an alpha channel the same happens as with the blue channel.)

I did some more test with this and I get the same problem with Light Mode to Blinn-Phong and Alpha and Emission connected but not the Diffuse.
