It is possible to 'draw' sculptural details onto heightfields with zBrush-style alphas? It occurs to me this would be a great way to block out shapes & such, and yet I can't really think of any way to go about doing it, nor find any examples of anyone doing similar...
- Hello all, So I know you can project objects onto heightfields etc. But want to make use of the heightfield erode node and a few others BUT not on the default heightfields; On a separate imported model. Ive tried converting my model into a volume and adding a height attribute which gets me so far but not the results that I would say are working at all. Was wondering if anyone had any ideas or thoughts or even reference/documents they could point me in the direction of?:) [I also tried unlocking the heightfield otl and inputting my geo into the volumes directly but I get a flat plane currently - but this flat plane is affected by heightfield nodes so I guess I just need to re-engineer the volume conversion to not just work as a flat plane but that could be a problem as I guess heightfields were made to work on a plane basis and extrude later on? - So heightfields work as a 2d volume and I imagine I'm going to need a 3d volume in order to convert my mesh into a heightfield ] - After looking inside the default heightfield nodes I'm pretty sure my process should be something like. - Import geo for heightfield - Convert geo to volume and give scalar height attribute, (and no doubt some other stuff I'm currently missing) - Use volume creation to make use of heightfield sops. Thanks C
