3ds max Lighting Previewing renders with ActiveShade . I’ve got a quad-core processor with hyper-threading enabled for eight virtual cores. I want to leave two cores open or two threads open and to do that I can set the threads value to six. I can just type in a six there, but there is a better way to do this actually. Which is to set the threads to a negative value which means Arnold will use all of the cores minus that number. If I want to leave two cores open, I’ll set the threads value to negative two and press enter. Now of course if you have a different number of cores on your machine, you might want to set these values differently but for active shaded it is recommended to leave two cores open, otherwise you may have issues with interactivity and 3ds Max. We can go ahead and do a rendering of the prospective view. Close the render set up window and with that perspective view active click on the render button on the main toolbar which is now labeled Activeshade. That takes a second but once it pops up we see an interactive production rendering.

Now there are no lights or material in this scene they’re just the object or layer colors but now if we change anything in our scene it will update in the Activeshade window. For example; I can navigate in the perspective view using the middle mouse button and that’s the pane tool that allows me to truck or pedestal around in the scene. In the Activeshade window updates automatically. There’s an even more intuitive way to use Activeshade in 3ds Max 2020. We can load Activeshade directly into a viewport just be aware that size matters. If the viewport resolution is higher then the Activeshade window then the rendering will take longer. Higher resolution will have an adverse effect on interactivity introducing latency when you try to navigate or change scene parameters. I’ll close the Activeshade window because Arnold can not update in more than one window or panel at the same time. Then go to the viewport menus, the third item from the left is the shading menu. It currently says, standard. From that menu choose the first item labeled Activeshade using Arnold. Now Activeshade is running interactively in that viewport. If we had lights or cameras in this scene their wire frames would be visible in this Activeshade rendering. Other then that as long as the right most menu reads default shading, you’re in a what you see is what you get, situation.


The viewport displays an image that is virtually identical to a final production mode rendering that has the same settings in the render set up window and it is fully interactive we can navigate in the scene using the middle mouse or maybe control alt and middle mouse to dolly forward and if we wanted to exit out of active shade just turn it off from the menu switch that off and that’s how to choose a renderer for Activeshade and do an interactive production rendering in a floating window or directly in the viewport.
