Rendering

In the seventh in our series of Blender 3D Basics classes, Ethan Davis takes you step-by-step through the rendering process in Blender.
As he shows you how to render your CG model to produce an image file, Ethan explains the different available render engines, plus the different components and calculations you’ll use.
You’ll learn about CPU vs GPU rendering, sampling, resolution, denoising, render passes and layers, and much more.
By the end of this class, you’ll be ready to turn your lipstick model (or whatever model you happen to be working on) into an image file.
You may also find it useful to refer to the Physically Based Rendering, Render, Render Engine and Samples entries in our 3D CGI Terminology A-Z.

    Hi Ethan,
    so when you ask us to go to edit and then preferences and then to settings, it then says i cant even select CUDA ( i dont have a graphics card just yet)
    it says,
    “No compatible GPU’s found for Cycles, Requires NVIDIA GPU withcompute capability 3.0”

    Let me know what to do about it
    Regards

      Hi Lamia,
      If you don’t have a dedicated graphics card (GPU) yet, you’ll have to go with the CPU rendering option instead.

    Hi Victor,

    For the render passes, you will need to follow the composite settings I used, this means not only enabling them in render passes, but attaching them to a file output and selecting a space for these to go. Now when you render, everything will automatically go into that folder, so no need to save individual passes. To get them into photoshop you will need to load every image, not just the base image as they are still separate images.

    In terms of an elongated image, I’m not quite sure what you’re experiencing but my only advice if the actual image is elongated is to check the camera settings are properly set, maybe even add a new camera and try that,

    Feel free to email the Karl Taylor team an image of what you’re experiencing and they can pass it on to me, or email me personally at and I can help you from there!

    Thanks 🙂

  3. Ethan, how do I save my render and export it into Photoshop? Sorry, I try to look up stuff that I don’t understand, but I’m having trouble with these.

      Hi Victor,
      For a simple single-layer render, you can just go to the “Render” drop-down menu and select “Render Image” or press F12. This will bring up the Render window, once the image has finished rendering you can then go to the “Image” drop-down menu and choose “Save As…” to select your file parameters.
      If you follow Ethan’s compositing techniques shown in this video, the same workflow applies, however you shouldn’t have to do the final “Save As…” step, as the File Output node will automatically save your passes for you.
      For the Photoshop workflow that Ethan uses, please see the next class here.
      Hope that helps, if I can be of any more help please get in touch.

      1. Hello Corey,
        Followed your instructions regarding the simple single-layer render. I choose Save As and selected my file parameters. Went into Macs Finder and dragged the file in to PS, No passes came with it. Checked the file output and all the passes were still there, just not in PS.

        Next, Tried Ethan’s techniques, again no passes followed into photo shop. So, I’m sure I’m doing something wrong. Checked my file Output again, the passes were still there, just not in PS.

        Again, I’m dragging the image into PS. What can be the problem?

  4. Ethan,

    Tried to test Render. I get an elongated image. Location and Rotation are all at zero. What am I doing wrong?
