Cant confirm here, using a
Ray Distance
of e.g. 0.08 gives following result here[also using a slightly fattened copy of the lowres as a cage also works fine here]
Marking as incomplete for the time being...
Here's what it looks like at 0.08.
Trying to use a cage gives me an error message: "Invalid cage mesh the cage mesh must have the same number of faces as the active object".
edit: Here's with cage selected and a distance of 0.08.
Hm, still cannot reproduce, maybe someone else can?
Is it possible the bake is not completing for some reason? I never see the status percentage go from 0 to 100. It usually stops at 1% - 7%, "completed", and then saves the normal map.
Not completing would make sense (output with holes expected then).
--debug-cycles
option and post the output as a .txt file here? [maybe there is something we can learn from that...]Marking as incomplete again until we have an answer...
CPU Compute
GPU Compute
Not sure how to do this, could you give me further instructions?
Seems like GPU only then.
Could it be that you are running out of GPU memory?
(if I look at my NVIDIA Server Settings I have it peaking at a little less than 2 GIGs -- which might be a little too much for the GTX 650 Ti...)
reg. the --debug-cycles option: open a command prompt in windows and run
blender.exe --debug-cycles
(instead of just blender.exe)btw: There was a change in GPU rendering since 2.79b [so only included in current master] that allows for rendering larger scenes, so you could try a recent build from https://builder.blender.org and try your luck...
My GPU does only have 1 Gb of VRAM, so that could be the case.
I tried doing this now, but my command prompt can't find blender.exe. I tried reading the wikihow article on how to add a program to the command line, but it reads like the person who wrote it has never spoken English or used a computer before. Maybe you can tell me how to add it and then I can debug cycles for you. In the meantime, it looks like I'll just have to render different things on my CPU and GPU as required.
You could just drag and drop the blender.exe into the command promt and add
--debug-cycles
to the endAlso: did you check if you can render on GPU with a new build from https://builder.blender.org?
Other than that, I think you are left with your CPU...
I disabled sandbox mode on Comodo and gave it a bake in the June 15 version of blender using my GPU and it worked as it should. Problem solved. Thank you for all the assistance.
Changed status from 'Open' to: 'Resolved'
Glad to hear! Closing then...
