Texture Error in iRay

harold_withers

Hi there, I'm getting a weird issue where my file when rendered in iRay is generating some weird artefacts on some textures. I get sqaures of colour rather than the material result I should be getting. Now from experience in other software I'm guessing this might be due to a memory issue due to having too many textures in there (It's quite a complex file). So is there a way to either increase memory dedicated to textures for rendering (the materials appear fine normally, only glitch on rendering), or is there a way to get at the texture files in the directory and remove the ones not being used in the scene?

 

Thanks in advance for any help.

Oh, and here's a picture of the render glitch so you can get a better idea of what I'm talking about. The error seems to manifest itself primarily in the red texture on the doors. They appear fine in the file, but when rendered this glitch appears.

memory increasing? not, but if the render start there still free memory in other cases you get a black render

also removing txtures from the folder its useless,  whats in the scene will fill memory not whats in folder

check the material that gives you the issue, try to change it

if you are talking about the red wall in the back, check if there is a duplicate object, indentical duplicate object gives a similar issue

also check errors in the log file

Sorry, rather meant removing the textures from where the available textures are called on within the file rather than from the actual texture folder. With the red texture on the smaller blast door there is an instance that does work, but most do not, but all the large blast doors their red texture seems to glitch. I'll do as you suggest and try reapplying the textures to see if that rectifies the problem.

 

Thank you very much for the response and advice.

You know what vukiol? You were right. Somehow I'd managed to duplicate these assets when placing them, so I had the previous copy with the old material applied and a current one with the new material applied. So mystery solved. God only knows how I managed to do that though. Anyway, thanks again for your input and assistance, much appreciated.
