Have anyone had luck with making VAT work with tangent-space normals, like the normals of the specific texture sets? Setup requirement is to use world-space normals. I want to use VATs material functions in Unreal Engine as an intermadiary which can be turned on with a static switch on a parent material, so that my child materials can use it, if they need. But of course, as is the standard, most of my materials use tangent space normals, for instance megascan surfaces. If this is not possible, this limits the usability a great deal.

Hi,

My goal is to import hundreds of small images and merge them into one bigger image, using different transformations and processing tasks. How can this be done effectively inside Houdini (can be via Python). Thanks in advance!

Ok answering my own question, maybe someone will find it useful: place python sop in foreach block, and in there:
your_cop_node.parm('execute').pressButton()
