Hi, In building a terrain, I used Entagma's tutorial on live rendering of Heightfields in Houdini using Redshift: The issue I'm running into is that my UV's are now super stretched on the terrain from using displacement on a grid. My terrain is huge, like 8,600 units across square. If I convert to polygons, it's pretty heavy. I'm trying to figure out the best workflow that will allow me to have the detail I need, but not be so polygon heavy. Would exporting out some lower resolution geo for rendering along with a baked displacement map be a good option? I need to be able to somehow edit the UVs as well so they are not stretched on my terrain texture. Any help would be appreciated. Jim
Hi, I have my heightfield exporting from Houdini into Unreal without any issues, but I can't seem to find any info on how to export the landscape holes. I can set the hole material, but not the actual hole itself. Does anyone know how, or can point me in the right direction? Thanks, Dave
Hi - I'm struggling to find a tutorial that explains the workflow for exporting a large heightfield terrain as tiles. I'm unsure where I would use a tilesplit/splice node for example - before or after my erode node? If I have a large terrain with many voxels, the erode takes a lot of memory. Can I use a tile split node before the erode to make the computation less demanding per tile, and somehow iterate over the individual tiles, exporting each tile's maps along the way? If I try to compute the erode on a very large terrain all at once, my pc runs out of memory. I would really appreciate any tips, links or advice you might be able to offer on appropriate workflows for working with large terrains and exporting tiled maps. Thank you Bryan
Hi I am trying to create a Heightfield Terrain with a single Hi-Res tile closest to the camera and as it is Houdini do this in a procedural way so that the tile can be changed dynamically, maybe linked to the camera. I am investigating doing this through a 'for each loop' but if there is an easier way I would love to know. The crop tool and the tile tools seem to be lacking an inverse toggle? I have probably missed something simple but if I work it out first I'll post the file for others anyway. It seems to me to be a useful workflow technique.
