Title: Corona passes trouble.
Post by: jkacza on 2018-01-24, 13:35:46
Hi there!! =D

Today I was experiencing a very annoying trouble. On my render interactive the zdepth works fine, but when I render something like this attachment (wild) appears.

Thank you!

Which version of Corona are you using (and is it Max or C4D)? Can you share the scene file, and does it happen in every scene or just this one in particular? Is the image what you see in the VFB, or does it look normal in the VFB after offline rendering, and this is how it looks on saving?

I'm using 3ds Max 2018 - Update 4 - Corona 1.7.2.
It occurs on this scene only, on VFB looks normal and I could save without problems. This happens only when I render or press F9.

Scene file had about 1,5 GB =(

So even with an offline render (not IR), it looks ok in the VFB, and only gets corrupted on saving to an image file? Which file format are you saving to, if that is the case (and let me know if I misunderstand, and it looks corrupted in the VFB too after an offline render, and only looks normal in the VFB with IR).

It works great on VFB and pressing F9, both I can save the renderings in any format
When I have "Save File" checked, this problem occurs, otherwise everything work.

I am try to save as PNG - 48bi with alpha channel non interlaced.

*Saving as jpg working fine this time* maybe a bug - before was not working

Could you try to save to other format, like TGA for example? PNGs are prone to errors/artifacts in 3ds Max.

Yes, I tried many formats... I realizied tha it's a random issue. Somethimes I had one pass good, other times I had two passes good. Now I am rendering 3 passes, 2 are good, for my porpose it's enought.
