Using Blender for a couple of weeks now and I must say that I’m very impressed about the cycles render engine
I’m currently working on an interior architecture project and I followed Blenderguru’s video tutorial about baking textures with Cycles. I basically want to bake all my shadows on to a hi-res map (2k or 4k maps).
It took quite a while to bake a 2k texture map with 24 samples, but considering my low-budget pc, I was quite satisfied about the end results. Then I went a step further and tried to bake a 4k texture map with 32 samples, but it didn’t work out. After more than 12 hours of baking, I gave up and canceled the baking job because I thought Blender wasn’t doing anything.
So guys, I’m wondering why it takes soooo long to bake a 4k map with high samples. I find this strange because I did Make Pan’s Cycles render benchmark file and it took me between 6-8 minutes to render his scene, while a 4k baked shadow texture takes ages. Why is that?
Here are my specs and benchmark results that I’ve posted in the benchmark thread:
CPU: Intel Core i5-2410M 2.30GHz
GPU: Nvidia GeForce GT 520MX
OS: Windows 7 64bit | Blender 2.71
Time: 8 min 12 seconds (GPU - CUDA)
Time: 6 min 36 seconds (CPU 4 threads)
I hope you guys can help me out, thanks in advance! (:
