I’ve been following Andrew’s tutorial on a nice earth, as found here:
At some point I noticed my rendered viewport would no longer update, it said my GPU was out of memory. Blender was using >3 GB whereas Andrew reaches about 200MB at this point (40 minutes in). A re-boot of Blender fixed the problem, I figure I had a memory leak or so.
Now, it still comes up with memory errors whenever I render using F12 (at 1920*1080 px where Blender jumps to 3.8GB) or have a viewport on “rendered” and change any node settings. I’ve got 6440 faces, a few textures which when appended take the total file size to 32MB. I use one of them as an HDR background. (Completely off-topic, any tips on how to use an image as HDR background, yet NOT make it emit any light? )
I’d appreciate if someone can help me solve this. I don’t think a 3.5-4GB GPU (Geforce GTX 970) should choke on a 30MB file, or am I missing something?
