Subject: Rendering buildings imported from Poser - blotches!


NanetteTredoux ( ) posted Fri, 20 March 2015 at 2:14 AM · edited Wed, 21 February 2024 at 10:03 PM

I am a Vue noob, please excuse me if I ask ignorant questions. I am illustrating a book and am using Poser for the indoor scenes and Vue for the outdoor scenes, because I want more natural looking plants. The building objects I made myself, they render perfectly fine in Poser. When I import them to Vue, I get weird blotches on the edges and corners, when I render, even at high render settings. I imported from a Poser scene file. It doesn't seem to matter whether I import with the Poser materials or whether I create new materials in Vue, the problem is the same. Blotches around the windows and the edges of walls.

Is Vue sensitive to the way an object is modelled? I have checked the normals of the object in Blender, and they all point outwards correctly.

I am using the Classic Day atmosphere which has global illumination. Is this problem specific to global illumination? I remember when Poser's indirect lighting was introduced some people had problems with blotches at edges and in corners.

The attached image is the house object simply imported from Poser with the Poser shader tree enabled, no other adjustments made yet - for instance, the scale on the roof texture (I have figured out how to do that), but my problem is the blotchy white walls.file_0e65972dce68dad4d52d063967f0a705.jp

I checked. It is even worse with an AO atmosphere.

It might come from phong angles. Double click the object in the Vue world browser and check the Smoothing angle value, hen raise it to 80°, it should fix it. Not sure all versions of Vue allow this

I've had something similar happen in Terragen and it wasn't flipped normals it was flipped faces....

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again

Thank you for that advice. I am going to try the smoothing angle first. I have Vue Complete, so I think I should be able to adjust that. So much to learn.

Hmmm...the smoothing angle was already at 80 degrees, so that wasn't the issue.

Ha! Turning mesh smoothing off made the blotches go away!

Sometimes the mesh is too "tense" because of chamfers and such. Turning smoothing off can work in such situations

I export from DAZ normally, but I have also from Poser. As a test, you might try exporting the Poser file as an OBJ. You will possibly have to change the bump and highlights in Vue. It will depend on the mat used. Since you model your own, you should have no trouble configuring it for rendering in Vue.
