Following PQ's video on Attribute Transfer. AttribCreate, AttribTransfer, etc were used by others all the time... I was still confused about their usage.
Grouping 2 points.
Grouping the remaining points.
"AttribCreate SOP" "num", value of 1 for the central_group and default value of 0.1 to the rest of the points (non_central_group). Creating custom attribute display after that, note that this is not displaying point number... these are number attribute created by "AttribCreate SOP"!
Seeing what the expressions are doing.
One more "AttribCreate SOP" for the other group, an expression (floor(rand($PT) * 10) + 2) was used to randomize number and at the same time make sure an integer is return.
Max sample count and distance threshold.
Blend width.
Lighting Workflow Tutorial
Reading a .pdf document on lighting, the set up was 3 point lighting (key, fill & rim) and basic navigation stuff but there were some useful tips inside. Related to depth map shadow, the controls like "Shadow Quality", "Softness" and"Shadow Intensity", most of the time i switch it on and leave it to default settings. Changing them to see how they affect shadows, and generating a shadowmap.rat for a single frame > checking off the "Auto generate shadowmap" so it reuses the map instead of generating a new one each time I render.
Sometimes it was hard to follow the pdf because this was done in Houdini 8.
