Hey everyone,

I recently switched from 3ds max 2012 to 2014 and since then have a serious issue with the materials in the render (plugin version v2.11.1a). It looks exactly like the old texture limit bug, when there was still a texture limit. Some materials are just displayed white/silver/red in the render (when rendering them isolated, there is no problem). It seems a bit randomly to me which of the materials are white in the rendering, because not all of them have a texture applied.

Reinstalling didn't help either. Please check if that is a bug, I am a bit in a hurry because I have to finish the project for a customer.

Does anyone else have the same issue?

Kind regards to everyone

We have a similar bug where different materials were randomly being applied to different objects. We found that making the affected objects movable proxies fixed thing, but yes not a good workaround to have to do.

Hey, thx for your answer. Sadly that doesn't solve the problem here, all the objects were movable proxies already, some of the materials are still displayed white in the render. Is there anyone else with that problem? Or is that a known issue to the octane team?

Can I have a scene to reproduce the issue?

Hey,

I can't send you the scene because it's huge and I am not allowed to hand it on to third party. I thought I figured the problem out in the last scene by deleting an object. After having deleted that object everything worked fine. But now I am working on the next scene and the same problem occured again. Only this time I don't have the object in the scene and really don't know what could be the problem this time. It seams to appear when a certain amount of ocjets are loaded in the render vieport and the scene reaches a certain size.

Here's what the render viewport says:
Memory: 3,713/4,929GB,
Textures: rgb 67, rgb64 0, grey 31, grey16 0

I attached two pictures. One pictures shows how it should look like (to get this picture I had to hide several objects) and one shows the error output. The error log doesn't say anything but pretends that everything is fine

Greetings

Hey everyone,

sadly I am still didn't get any further with my "texture bug". I really don't succeed in locating the error because it appears randomly and also takes the leafs away from my forests (Plants are set with Itoo forest Pack). Here is what I've already tried:

Increasing the rayepsilon value didn't help.

Then I checked the info channel kernels. The "geometric normals channel" looks quite normal to me, but the "Shading normals channel" gives a similar picture as the faulty rendering. I attached three pics, so that you can have a look: "01_error", "02_error_geometric normals" and "03_error_shading normals".

Then I found out that the error changes with making or unmaking things movable proxies. I attached another picture ("unmade proxies") to show you that the materials shown in the rendering for the front of the house and the windows are now shown differently after I unmade the belongig objects movable proxies (rest of the scene are still proxies and I also need most of them to be). I attached another two pics to show this: "04_unmade proxies" and "05_unmade proxies_shading normals".

The scene is huge (2,4 GB). Is there a possibility to send such big scenes? The problem is, if I reduce the file size by deleting geometry, the error doesn't occur (as soon as I hide some high-poly geometry, the error doesn't appear in the rendering).

Hey Karba,

did you get my e-mail with the download-link for the scene?

Hi

I got it, but didn't have a look yet. I just came back from holidays. I will have a look soon.
