Chaos Corona for 3ds Max => [Max] I need help! => Topic started by: waterpls on 2024-12-22, 02:41:25

I downloaded the corona material library and added some materials from there onto my objects. But only the materials with high refraction show up in the render, everything else looks fully white. Now this would still be fine, but there are some materials that don't let me change the refraction, so they are unusable. Anyone know what the problem is? I'm still very new to this. I'm using the newest versions of corona and 3ds max
I also need to add my own image as a material, anyone know how to achieve that? The only way I know how to do that is to drag the file straight onto the object, but obviously at the moment it doesn't show up, because of the refraction

Hi,
Could it be the same issue like in this recent topic on the forum: https://forum.corona-renderer.com/index.php?topic=44114.0 i.e. your objects might not have proper UV mapping for the textures to be visible?
-
I saw that post, and I indeed did not have uvw maps on my objects, however even after adding them, they don't appear
-
Are textures not visible only in viewport, or are they're missing when rendered as well? You cab create box primitive, make sure that generate mapping coordinates is checked in command panel, assign that same material and see if textures are visible now. Try it with real-world map size option On and Off. If at any stage you will see the textures in viewport and/or in rendered image, then you will know that the issue is with your object's UV mapping, otherwise it could be that something wrong with material, maybe texture paths are missing, or something else. Let us know if that solves your issue or if you need further assistance.

The textures are only visible in viewport, that's the problem. They don't appear in the render, unless I increase the refraction level.
I tried adding a box with a uv map, as you described, added the beige carpet texture from the corona library and it doesn't work, it just appears fully white. Then I try something like the black porcelain texture, it also doesn't work, until I increase the refraction to like 0,1. And texture paths also aren't missing

At this point i think it would be best if you could attach some pictures to illustrate the issue. Show us the rendering and screenshots from viewport, as well as render setup and material settings. It might be that your render is overexposed to the level where no texture is visible only blown out contours of the objects, it might be something else, but it would take too long to guess it from verbal description alone.
