      Hi everyone,

      I’m following a CG course for creating a realistic human character. Everything was going fine, but I’m stuck at the emission baking step used for baking pore details onto the face.

      The instructor’s settings and my settings are exactly the same, but whenever I click Bake, Blender runs for a while and then completely quits/crashes without showing any error message.

      What I’m doing:
      Baking Emission Map for face pores

      Following the exact node setup from the course

      Texture size: 4K

      Margin: 10px

      Cycles → GPU Compute

      What I’ve tried:

      Restarted Blender

      Reduced bake resolution (same issue)

      Disabled addons

      Tried CPU bake and GPU bake

      Tried a fresh .blend file and appended objects

      Increased undo steps + memory settings

      Issue:

      Blender closes suddenly in the middle of the baking process with no crash report.

      My System Specs (New PC):

      Processor: Intel Core i9-14900KS

      Motherboard: Gigabyte Z790 UD AC

      GPU: Gigabyte RTX 5070 Windforce 12GB GDDR7

      RAM: Corsair Vengeance 64GB (32×2) DDR5 5200MHz

      Storage: NVMe SSD

      OS: Windows 11

      What I need help with:

      Why is Blender crashing during emission bake?

      Is it a GPU/VRAM memory spike issue?

      Any recommended bake settings for high-detail pore maps?

      How can I check proper crash logs?

      Thanks in advance for any help!

        Hi Aashish @aashishpatel ,

        Have a look at this: https://docs.blender.org/manual/en/latest/troubleshooting/crash.html 

        Or a similar page for the Blender Version you are using.

        If you want, you can upload your .blend file (Pack all Resources!) to Google drive, Dropbox, or so and post a link here, so we can test it on our hardware..

        Please, also tell us what Blender Version you are using.

          What I usually do is just render or bake on other different Blender versions. Chances are whatever rogue 0 or 1 that is causing the crash, isn’t there in other Blender version. What I also do is import or copy paste all my stuff into a brand new .blend file and usually if it’s a bug on my file, it wont be there on a brand new one.

              Hi Aashish,

              Sorry, but that doesn’t provide me with any new information (apart from the Blender Version).

                I have uploaded my Blender file here for reference.

                  What I do notice, is that you don’t have an OSL checkbox and your ABove Surface is greyed out:

                  So maybe it’s an Addon you’re using?

                    I’ll have a look at your .blend now

                      That OSL option is only available when using OptiX. I am using CUDA, and I don’t use any addon. And that above surface option only available when you have camera in your scene, so right now i do not have any camera so it is disable.

                        Okay, 

                        So it Bakes fine on my PC.

                        That Above Surface is greyed out  for me as well, so we can ignore that.

                        Might be an Addon, like I already mentioned (this is not unlikely).

                        Or you need to update your Drivers.

                        Or it’s something else…???

                              Maybe…it’s a Windows thing? 

                              I heard someone complaining of 5.0 (Release Candidate) crashing on a Windows machine…

                                Have you tried disabling Blenderkit?
