Now open all the render elements in Photoshop as a layered PSD. You’re saving the rendered images via the V-Ray Frame Buffer, so there’s no need to use the 3ds Max render output.įinally, click Render and you’ll notice in the V-Ray Frame Buffer that you can view each individual render element in the drop-down list that’s located in the top left. You can choose to save out as 32-bit colour, which greatly improves the accuracy, but this will also mean larger file sizes. Saving in anything less, such as 8-bit or a lossy compression type such as JPEG, will mean too much colour information will be lost and the composite won’t be correct.

Choose TIF as the image file type and set it to 16-bit colour. Click Browse and point to a location to store the render elements. Untick Save Alpha because it’s not needed, but keep Save RGB ticked so you can compare the composite against this. Scroll down to where it says Split Render Channels and tick Save Separate Render Channels. Next, in Render Setup go to the V-Ray tab and click to enable the V-Ray Frame Buffer. However, for calculating accurate lighting and materials, you should always use gamma 2.2. Any other gamma value would cause the render elements to be incorrect. This is because when compositing in Photoshop or After Effects the calculations are also done in linear space. Firstly, the render elements must be saved in linear space. One incorrect setting could cause the composite not to match the intended beauty pass.

There are a few settings that need to be set in Render to render out each element correctly. Open 3D World 0164 t_Q&A_164_Max-vray.max from the files accompanying this Q&A. Here, I’ll cover the necessary render elements that make up what’s commonly referred to as the beauty pass. You can tweak the intensity of a reflection, change the diffuse colour and even adjust light intensity. By rendering out each of these elements as a separate image file, you’re able to control every property individually. Each element corresponds to a specific property, such as illumination, shadow, reflection and refraction. A complete rendered image is made up of various individual layers called render elements.
