Hi guys,

I got a question about the split tile workflow with Heightfields.

I have a large area that I am slicing a bunch of times and resampling based on which tiles are closer to camera that I want to get more resolution out of.

In between split tiles there are apparent seams and the option to “Tile Lower/Upper Overlap” is great because it has the right idea to fill in the gap but it doesn't exactly do the job for me. I am still getting obvious seams.

Here is a screen shot below, this is 2 split tiles merged together with “Tile Upper Overlap” value set to 1, which connect the two separate edges but still leaves a seam.

Let me know what are your thoughts and if there is a better workflow for what I am trying to achieve.

Cheers!

Hi guys,

I have a pretty straightforward question but can't seem to find a simple solution to it.

I have a large heightfield grid and I want to crop a section with a Box using the heightfield_crop node. Which gives me the attached image. All great, but I would love to be able to do the inverse of this selection using the same box. That way whatever is inside the box, I can upres and the rest can stay at a lower resolution. The crop node doesn't seem to have our usual “Mix Method” options.

A few things I tried was to do an extrude of the box and inverse the crop object itself but that didn't work because the bounding box stays a solid shape regardless of what's inside.

Tried to convert to volumes and subtract with a volume mix, no luck either.

Let me know what are your thoughts, I am pretty new to HeightFields so i might be missing a handy node that does exactly what I want. Sounds straightforward enough..

Thank you for your time.
