Hi, I have used shininess and emission successfully, but it must have been in things where I didn't notice the large scale effect it was having. So if anyone knows of something I might be doing incorrectly, I will be happy for advice.

 

Note - I have tried with both jpg and png files including png files with nothing but the thing I'm wanting to reveal. However, I noticed that studio automatically adds a black back to a non square/rectangular texture.

 

 

When I have used an opacity map for transparency, I can only get the correct results with shininess and emission if I use Alpha Test. For anything that necessitates composite blend, the entire texture is shined up even if it isn't showing. This seems to be true in additive mode as well.

 

When I want to use shininess/emission without an opacity map, such as in the room example i posted here, it just doesn't seem possible. I can see that it can still be useful in the right situations where xrfs are more isolated. I did also attempt applying shininess or emission to all of the materials, and it did create more of a uniform look, but in fact it completely undid the mood I was looking for, and made the individual walls stand out even more from each other. Perhaps I'm asking too much for the current status of studio/next!

This is a High Quality Pain in the Butt.... Its been happening to Shoes and clothes. I need the shine where it is suppose to go not on the whole mesh.. I have tried everything to get this from happening. we need a fix for this or I wont be using shine anymore.

Thank you @4u​ , I appreciate your insights of experience and love your products. I decided that the best solution to this issue was to not rely on a plane with opacity design and shine since the shine affects the entire plane, but rather to create the design itself as a mesh. Something you seem to do all the time!

Some basics to check.

Texture, opacity and emission maps are the same dimension size, eg 256x256 square

Opacity and Emission maps are within an 2mm border of the image, I always leave a gap as so many meshes bleed that last pixel or two.

Thank you for your response, @jazzKat​ and for your amazing videos without which I don't think I could have done anything! It's reasonable to expect that there are limitations to the things we layer on a texture so as not to avoid rendering issues. I was just hoping it might be that I was missing some vital piece of information!

Yes this is an issue when using Composite Blend (none alpha-test). Might also be compounded by using Shininess (any shininess you might want to see won't be visible with emission in place). Its a rendering issue so not sure there's anything we can do to correct the problem.
