Today I was rendering up a storm and I got this error afterI ran a radiosity today.
Renderer: File parse error
File: Obj_2811_1_0.ent
See photo attached.
If it does not repeat, I'd ignore it but be sure to have a back-up copy in case you need it later. PC's glitch now and then and do not repeat the same conditions...not often/rare, but it does happen as things run in the background you may not be aware of...such as a virus checker.
If the problem occurs at every render, then most likely you have a bad object construct. I'd suspect any imported items first....delete one at a time until problem found.
Think back to when the problem occurred and what you did last to change the drawing/objects and that is probably the suspect object.
