I have used blender off and on for ~20 years (more off than on)… I recently wanted to show introduce someone to using it, but instead I’ve become stumped with the results I am getting.
To try to get a handle on things, I dropped back to rendering the default scene and tried to start working from there, but it too gives me nonsensical results for 2 out of 3 rendering engines. (I am on Linux Mint)
Opening 2.76 to the default scene and immediately hitting F12 results in this:
<an image that makes sense, I only get one image per post at this point>
Opening 2.82 (downloaded yesterday) to the default scene and immediately hitting F12 (apparently Eevee) results in this:
Switching 2.82 to the workbench render and hitting F12 results in:
<another image that doesn’t make sense, I only get one image per post at this point>
which doesn’t make any sense given the position of the light.
Switching 2.82 to the cycles renderer and hitting F12 finally results in something sensible:
<an image that makes sense, I only get one image per post at this point>
Naturally, I’m ultimately trying to do something beyond just render the default scene, but with the difficulties I’m having on 2 out of 3 rendering engines on default settings on the default scene, I’m not even sure where to begin troubleshooting what I’m really trying to do.
It’s undermining my attempts to convince others to give Blender a try. Is there somewhere I can read up that will give me the way of looking at things that helps this behavior make sense to a potential new user?
opening the default blend and rendering should produce near identical results for eevee and cycles. your image looks exactly like the default scene with the light turned off.
workbench does not use scene lighting, it is equivalent to the solid shaded view from 2.79 and earlier.
you’d have to save and share your blend file to examine, even if it’s supposed to be the default, because that behaviour is not expected.
as a final thought, the system requirements for blender changed when they jumped to 2.8. if you have an older system, there is a possibility your graphics card might not support eevee, causing the dynamic lights not to render. you can check here to see if your system looks to meet these requirements:
I’m suspicious it might be a min requirements issue, then. Is there any feedback that Blender gives in log files, etc. that the min graphics card requirements are not met in Blender’s opinion? (From the point of view of bringing in new users, this kind of feedback seems good to provide.)
The link you provided mentions-- Graphics card with 1 GB RAM, OpenGL 3.3
From glxinfo -B, it’s unclear what my RAM/OpenGL information actually is.
Regarding OpenGL- OpenGL core profile version string: 3.3 (Core Profile) Mesa 19.2.8 OpenGL ES profile version string: OpenGL ES 3.1 Mesa 19.2.8
Regarding RAM- Total available memory: 1533 MB Currently available dedicated video memory: 511 MB
(I seem to be failing at using markdown on this board… triple backtick isn’t behaving the way I expect…)
