Arthur abeen prepared a breakdown of his howl s moving castle fanart scene discussing in detail blockout asset modeling texturing lighting and more. So far my workflow seems pretty linear but from this point when i finish painting the diffuse map it s pretty much just abck forth between modeling tweaking diffuse normal and all other maps and developing the shaders bit by bit until i. Create the spheremask and plug in the component mask to b. Resize it so the grout can mask the seams.

Add an absolute world position into a and set the radius to 256 you may need to increase decrease this value based on the scale of your scene. In ue4 i will have to set up an environment with proper lighting and hdri to troubleshoot and preview other maps such as roughness specular normal. From the parameter drag off and create a component mask for rgb we don t need the alpha. If you wanted to take this to the extreme constant bias scale the noise map to 1 1 as if it was a normal map then multiply it by a random seed value to get the most bang for your buck.

Ue4 has had material based procedural noise for some time now but most users have had to limit their usage of it due to its high performance cost. In the ue4 packaged material function i specified this using a min and max. You can make the grout whatever color or texture you want.
