In the video tutorial, go the sequence where I explain how to open the HDR image. To increase the intensity of the lighting provided by the HDR image, simply increase the strenght - currently set to 1.000. Did you try to set the dimensions maybe to 25% to see if you can render a smaller complete image before it crashes? If it is unticked, you won't get them but the rest shall be fine. I use it for the shader rounding the edges. It is much faster but doesn't work with all types of shaders. The reason why I asked for the graphic card is that there is an option to tick in Blender to use the GPU instead of the CPU for rendering. Thanks in advance for your help ! Thank you for your advice ! I have a GTX970 graphic card, so it's more than enough to handle my model. How many do I need in average to have a clear smooth render ?

The samples for my render were set to 1200. How do I add a little bit of gain on the HDR image ? It's pretty easy to do while rendering in Luxrender but I didn't find the big 'Add intensity to the light' button in Blender.įor the grain on the picture, I think it's because the samples were to low.

I tried to add a sunlight but apparently that did not work. My render had some problem, the image was a little grey, and grainy. So yeah, my experience with Blender is not great so far, but I've made some progress ! The render did not crash when I unticked 'Open Shading language' but I can't show it because I've stupidly close the Blender console and the whole software close with it. In the camera viewport, press Ctrl+B and select the area of the camera you want to render. You can also only render part of the image. Create a new material and select Emission. You can also attach/mix an emission shader to a mesh. Add button (or Shift+A) and choose type of lamp. Yes you can also add as many lights as you want even with a HDR lighting. What kind of graphic card do you have? Is it a NVidia CUDA capable? If you want to render faster for testing purposes, you can try to decrease the number of render samples in the Sampling section to something like 100.Ĭan you also try with smaller dimensions (either by changing X and Y and simply by turning down the percentage scale number). There are lots of shortcuts to learn!Ĭan you try to run it with Open Shading Language checkbox unticked? - It is located a couple of lines under the Render button. Yes, Blender is not the easiest to understand at first.

Can you run blender on mac desktop
