[Render workbench} Getting it to work on Windows!

[howetuft]

Thank you for your feedback, I understand there may be some documentation effort to do.

Sure where should I make a wiki page in the freecad wiki that you can review when done?

[Markymark]

Just as a hint: The wiki is already pretty clear about that as long as we talk about the wiki of the workbench on github.

I am struggling with POV-Ray rendering a simple cube at the moment:

Code: Select all

Renderer command: C:/Program Files/POV-Ray/v3.7/bin/pvengine64.exe +P +A +W800 +H600 +OC:/Portable Apps/FreeCAD/FreeCAD_latest/temp/FreeCAD_Doc_8e6646b9-00ea-40a2-b77d-3433433d4358_fe5d78_3428/PovrayProject1q8sux5j.png C:/Portable Apps/FreeCAD/FreeCAD_latest/temp/FreeCAD_Doc_8e6646b9-00ea-40a2-b77d-3433433d4358_fe5d78_3428/PovrayProject1q8sux5j.pov
08:51:38  Running the Python command 'Render_Render' failed:

Could not load image file

Luxcore project runs like a charm. POV-Ray throws an error. Did not invest much time in that so far. Any ideas? File enclosed.

Thanks in advance. m.

I checked your file and I had an issue with the correct location of the Povray template.
After I fixed that it worked for me, i got a blue cube.
I guess you use portable version, but I got the same error when this was broken.

I also had run the Povray installer but I forgot that I already had setup the portable povray version, soooo I am using that one. But maybe you can try to run the povray installer.

Yes, you have to update the path. Would be better to have a relative path here.

Are you talking about the portable version of PR or FC? I installed PR and it runs without problems with the "POV-Ray-Rendering" workbench. I run FC portable. The .pov file in generated in the /temp directory of FC with no problems. It is just that no image file was generated. I already checked that there are no blancs in any paths (this is a problem with the Appleseed integration). Still get the same error.

OK, just found the issue. This workbench has major problems as soon as you have blanks in paths! PR installs to "C:\Program Files" ... thats enough to run into the problem. Appleseed has the same issue. I will try to warp my head around this.

Just create a markdown file in 'docs' folder in github repo (send me a PR), I'll add a link to it in the main page. Thanks!

I agree with you (relative path), the absolute path prevents portability, I'll try to think of a solution to this problem.

I have cycles working on windows!

It looks good, at least it looks the best of all the renders!
But it needs a lot of tweaking. But the basis is there.
First thing I really would like to change is the ground plane, it should be infinite or it should look like it is infinite!

I have uploaded the cycles stand alone build for windows here:
https://github.com/HaasNL2/Cycles-stand ... dows-build
After you download it you just have to edit the render workbench settings and point it there.
The resolution it renders is the resolution your window has.

Great job! You can rest on the chair, now !!!

First thing I really would like to change is the ground plane, it should be infinite or it should look like it is infinite!

Ground plane feature is aimed at being super-simple: one-click, no tweak - it is automatically sized on the scene bounding box.

Then, if you want a more elaborate plane - other size, orientation, material etc. -, just create a plane in FreeCAD: https://wiki.freecadweb.org/Part_Primitives
