Reflection artefacts

[werner.poetzelberger]

Hey.

Sometimes I get weird reflections on objects like leaves.

In this case it is a skinned char. with a very faceted surface. Some of the faces reflect the environment extremly bright, even, when setting the roughness to 1.

I know, that when setting specular low or 0 then these bright spots disappear, but then I dont get specular on the other faces as well.

It is just like, that this appears kind of randomly. But in fact these are faces, which relfect the skydome extremly.

I had the same issue when creating Leaves for trees. For some reason I cant get rid of that phenomena.

(more visible, when using bloom)

Some ideas?

Thx.

Werner

Hello Werner,

We examined attached screenshots and the first assumption was about incorrect normals. However, to say more our artists asked for the content. May I ask you to send mesh, textures, and materials?

Thanks.

Hey.

Thank you.

i am uploading to your ftp (/CHARACTER).

There are 3 meshes. And an animation fbx file (which scales the character by 0.01), just you know.

Materials and texture included.

It occurs regardless Normal maps applied or not.

Hard to say. Maybe you can analyze a bit better than I can.

Best. Werner

yes, I think it is something with the normals, these faces point into a direction, where the sky is reflected.

But it occurs in a way, which is not really understandable (or it is because of the skinning?).

Weirdly, these faces behave soo much different compared to the others, thats the main issue.

Looks like an issue with the geometry. We've put a plane near incorrectly rendered polygon, you can see that normals are broken.

So it more of a content issue.

Yes. I saw something similar right now.

When I look at the world normals, there shouldnt be any yellow.

Hmm. argh. 

Thank you for checking
