    Dimension has never been tested with eGPUs. There’s probably no reason we can’t support them, just haven’t today. At this time we don’t have immediate plans to add this to our testing coverage, but I’ll bring it up to the team and will update here if we start work on it!

    A note, it’s not actually expected that plugging in the eGPU afterwards would change anything. Dimension selects the GPU at launch and once selected doesn’t change. I’m very curious about the performance change, but if it’s actually using the eGPU that is not by design.

    I don't even necessarily mind that it isn't supported, but I would like to be able to start the program without messing with my setup. Although, I understand that even that may be difficult.

    I can't say definitively that plugging in after helped, but I can explain my experience with the issue. I have a Mac Mini with 2 external monitors. One is plugged into my Mini, and one is plugged into the eGPU. I can't start the program unless I unplug my 2nd monitor. My roommate has an iMac (with good but inferior specs) and uses Dimension for product rendering. I lent him my eGPU and he hooked it up to his 2nd monitor and rendered there (Dimension was already running when he plugged it in). He was reporting 20 minute render times for his scene and with the eGPU hooked up, those dropped below 2 minutes. I can do some more closely controlled tests if that would help.

    I do think it might be smart to consider adding eGPU support. I'm a graphic designer and a Mac user. Many designers right now are looking for 3D Lite options that don't require switching to PC or learning intense software (C4D, Maya, 3DSMax etc.), but still allow us to do simple things like product renders, 3D typography, realistic lighting & shadows, etc. Macs have notoriously bad graphics cards for their high prices, however. I expect eGPU's to remain a popular choice for tweeners like me who can't afford a 20k Mac Pro and/or don't want to switch to PC. I would think this group would have significant overlap with the same people looking to use Dimension for the previously mentioned reasons.

    Thanks for the prompt response and for working to make our lives easier! Watching my roommate go from painstakingly painting shadows in Photoshop to rendering them almost instantly in Dimension has been quite fun.

    Hi all! I just wanted to give a quick update, since GPU rendering has been out as a beta for a little while. The initial beta was built on NVidia Optix backend and only worked for some Nvidia cards. Thank you for all of the feedback so far!

    One issue we’re hearing is that the GPU renderer errors out and then Dimension doesn’t show the GPU as supported again. Updating to the latest video card drivers is recommended and may resolve this issue.

    We’re actively working on rebuilding the GPU rendering in a different way, so it’s available to all users across all hardware (Nvidia, AMD, MSI, etc).

    We’ll update the status here as we get closer to a beta of the next version of GPU rendering.

    I can use my eGPU to render but only if I start it after Dimension is already running. If I start Dimension with my eGPU enabled, I get an OpenGL error message. This seems like a simple bug in the initial System Requirements check that the program performs. I'm hoping there are plans to fix this, but it seems the problem has been around for awhile.
