The pink color means missing texture. So you probably textured that area and then move your files to a different location and Blender doesn`t recognize your file path.
Hi guys, thanks for all the replies! I have removed and re-added the image from source, nothing has changed. So instead I tried selecting 1 object rendering pink, and then selecting inverse and deleting (minus the camera).
So this does kinda suggest what was said about hidden objects. However I have made sure every single item in my scene is not hidden, and moved the post, nothing there.
I have tried deleting objects randomly, and this has caused changes. In my scene there is a small model of a light using both a diffuse and an emission material.
It’s small and out of the way, has been in my scene for days without causing problems. It has not been changed in anyway recently.
If I delete this object, then I get the following change:
Could you try using a more recent version of Blender? 2.73 was released early 2015…
Do you render on GPU or CPU?
And how many textures are in your scene? IIRC there was a limit on the texture count available for GPU rendering. If you exceeded that, the additional textures rendered as pink, which might explain why deleting objects makes some textures reappear.
Thanks. Switched to CPU and it works, must be the texture limit. I have a HUGE number of textures in the scene. I suppose there is no alternative solution beyond:
carefully hiding what I don’t need for each render since there is a lot of hidden stuff depending on my camera position
