  1. Hi, Im new to arnold for Houdini and want to know if there is a way to directly specify a vdb volume in the string path instead of a file on disc. for e.g.: I tried: /obj/cloud/OUT op:`opfullpath("/obj/cloud/OUT")` op: /obj/cloud/OUT ( without any luck) thnx for the help!
  2. Hai, Is there a way to get the data of the length from a alembic? I have to run a pipeline where I export the exact amount of frames as coming in. THNX
  3. Hi guys, Far far far away, in a galaxy... there was someone that had a tutorial online about morphing a text into a logo. He did some font fixing, creat a trail of the morph, some rendering mantra stuff.. It was coming out at the same time as the CMIVFX ParticleFx tutorial. I know its a old one but I am looking for it but have no clue what the name is / or which company. Anyone? Im just looking for that specific name, not a solution to fix something ;-) thnx
  4. Auto UV crashing?

    Hi auto UV is constantly crashing in H16.5 and H17. working wth the v1.72 of the gamedev tools. Am I the only one? I want to quickly do it on a car mesh around 600.000 polygons. thnx
  5. Houdini rendering Geo, renderflag

    Thnx for the reply. No it wasnt about rendering, it was about saving geometry with the file node and click render where the render node was not at. Its seems like I found the whole problem. It is because I had made the project first in H14. wich is based on the old foreach method. I cant show you the exact way but here I give you the H14 problem If you switch to newer versions. The older version is a subnet so it can have render flags on different things and will output the renderflags While the new houdini workflow just export wherever you set the ropfile node
  6. Hi, I have some basic question. How to convert a glossy reflection file texture to a rougness map using principle shader?... I know its the invert of it. I tried different things... add a minus to the roughness slider at the top level (didnt work) Allow edit of content -> Adding a invert Node to the roughness node (gives a red "!") Allow edit of content -> multiply by -1. (gives a red "!") thnx
  7. search and check for UV's in scene

    Thank you both!! The wrangle is realy easy to read! It should be: float test = max(@uv); Also it gave me by testing it on a unwrapped cube one value on the spreadsheet of 0. But by promoting it, it luckely disappeared. Hopefully it works on the rest of the stuff now. uhmmm... damn nope it didnt realy worked as expected... there are some objects that are just getting deleted who has uv's. if(test != 0) // did some fix too.. Im almost there float test = abs(length(@uv)); //gives me also some result for uv's that are placed in a negative uv sheet: i@hasuv = 0; float test = abs(length(@uv)); if(test > 0) {@hasuv = 1;} Now Im almost there... How to find overlap procedurally? Any idea? scene2_uvCleanUp-ViaWrangle.hip
  8. search and check for UV's in scene

    Hi, I have large scene with alot of geometry wher some have UV's and some who doesnt. I imported the whole scene as one obj file so it thinks it has UV's. I know there is a way to determine if it has to uv's I saw in the simple baker that it has a switch that unwraps the model if it doesnt have any: haspointattrib(0, "uv")||hasvertexattrib(0, "uv") But this doesnt work. because it has a attribute uv, which is empty on some object. Is there another way to look for objects that doesnt have uv's? or where the uv attr views none uv's? thnx
  9. Gamedev Simple Baker

    I got the last version, 1.11. Shortest path and cluster doesnt work at all. Only the Standard uvunwrap.
  10. Gamedev Simple Baker

    Thnx for your help mate!!! Now it works. Dont know what the problem was. Maybe the visibility, maybe not... cause I did get the occlusion and normal out of it. maybe it was just the gamedev tool. Also strange problems with the autoUV tool now. seems like it is still a bit buggy.
  11. Gamedev Simple Baker

    I noticed it was just linked and not more then just a simple hda /otl. but both doesnt seems to work.. would love if you or any other could figure it out what is wrong. THNX Davpe! In the file: In SOP game dev.. I get the lines for displacement. Normal and OA for example are just fine. in the ROP(texture baker): All is getting black... simpleRockBakerExample.hip
  12. Gamedev Simple Baker

    Thnx, I did a search andn that seems to work the sameway as the tool except its in sops, but this gives me just black images for everything now... (using exr / tga for now).
  13. Gamedev Simple Baker

    Hi, I try to bake some heightmap but I get some weird lines. Does anyone knows what this is? Tried to install different versions of the gamedev tools, Tried adding my own distance, adding samples, different file formats.. but without any luck. thnx
  14. Export pyro to polygon alembic with vertex color

    THNX for your fast reply. I understand what your saying but thats not totally true. (but i tried to change the name to see if that fixed it, but no luck) If I test it with a grid > color it > use a object for transfer color attr. > promote to vertex color > and export with alembic it works in viewport. I just need to set my colorSet to Cd for render in arnld, e.g. But, if I try it by another object in my colorSet editor I see the attribute named"Cd". If I do that with Pyro converted polygons. there is no attribute listed in maya. read the file back in Houdini it gives me the color though...
  15. Hi, I was trying something stupid but it doesn't seems to work. I converted some pyro to polygons. Get the Cd heat from volume. Promote it to vertex color. Export to alembic But the colors aren't visible in Maya when I import it. If I do it with some other object. It works. Do I overlook something?
