How can I setup the glass material to render the back of the glass? The material is made of one texture (glass and rope in the same). Should I make a seperate material for the rope and for the inside of the glass? or is there a setting I missed?
Had been really good to have like a short video in the documentation that explained this. Feels like this is a common question but I cant find the correct answer.
I would separate out the glass geometry, disable cast shadows on it and enable doublesided on the material…
Hello, so yes first I advise that you use a different shader for the ropes and for the glass, and use an opaque material for your ropes, this way, the ropes will be rendered before the transparent pass and you will have no problems to see them from the inside of your jar. For the glass, good idea to remove cast shadows if your glass will be very transparent.
for the materials you can do something like this :
With your different texture as input if you have them. For texturing, making the border at the oppening of your jar a bit more opaque will help making that more visible. If you have sorting issue you can use “transparent depth prepass”, but you will loose what’s behind the first surface the camera will see.
What I like to do, and this is more of a workaround than anything, is to stack the same model twice, and having one that does refraction, and one that doesn’t, this makes the inner details more visible. I’m on the artist side, this is me bending the rules a bit to achieve a better visual result. This will makes your model heavier on performance.
