Title: How can I make a realistic epoxy floor?
Post by: bnt8 on 2018-03-24, 17:17:39

Hi, I'm a newbie to Corona, and I would like to have similar to the attached file, so i'm struggling with reflection and glossiness map but my results are pretty disappointing.
The texture may be part of the problem, it's a stucco texture i'm manipulating with c4d tools, but I think this material is not simply made by diffuse and reflection.
So, do you have any suggestions?

So the attached is your reference? Can you share your results? That would help with feedback. ;)

I just think you need to break up the spec, gloss and bump channels with a grunge map.
That should do the biggest part. I'd also add a second layer of specularity to it. Ze SSS is negligible hier.

Yes, that one was my reference, here is my result, but i'm not even close.
In this one there's no bump as i'm looking for a right texture, it continues to reduce glossiness too much.

I'm also trying to make some layered material but i don't know how to add a reflecion only layer

Well if you want to share the file at all that would be useful. I had a quick play but haven't really looked into epoxy floors as yet. I always thought they were super glossy.

you can't just add a reflection layer only. sorry, should've mentioned that. you have to copy the diffuse into the second material that goes into the layer material and mask the parts with either bitmaps or shaders.

Hopefully making layered shaders will be made much easier when we get the node system. Really cant wait for that.

Sorry i had many new projects to work on and had to stop this one for now, here is the single layer material i did.
Didn't know node system is coming, I hope I understand it soon

I can see that you haven't exported your layered material properly. It's missing the base material plus layers 1 and 2.
