  1. Hello Everyone. Im trying to test my foam particle settings on my ocean but every time I change a setting it re-creates the ocean displacement taking 7 mins each time before it starts to render. I know I can bake out the displacement, but how do I attach it to the ocean surface shader so it doesnt re-create it every time I change a setting.? Or am I doing this totally wrong and there is a better way?
  2. Bake Textures

    hey guys, I did this test scene with a low poly and a high poly spheres (I also did a cage but it made no difference) the most important problems are: - (i think) it looks wrong if the high poly faces are outside the low poly surface (i think it's the darker areas on the map) - I can clearly see the low poly faces check it out, here's what I get using the bake texture rop: this is the Tangent-Space Normal (Nt) (displacement have the same problem) and that's how it looks like rendered with tangent normals applied. I will alse need to bake a procedural diffuse color but I'd like to focus on those other problems first. Once again, thank you /Alvaro Bake.rar
  3. Hey, I have to work a a pretty huge ship szene. Unfortunately I can't really give out the spectrum file or the masks because during the baking process all my memory gets eaten up (64 GB) what ends in a crash. So we are talking about a test situation with only 1 million flip particles. I also decreased the mask resolution to 0,1 and tried ‘use input volumes only’. The flip domain itself is very huge (400-600 m).So how could I save some memory during this process or even make it work at all?
  4. Alright I'm still quite new to Houdini but I'm enjoying its shattering system and its dynamics are much more viable to use over the likes of Maya. My question is whether or not it is possible to bake object shattering and interactions with other objects as set keyframes. Reason for this is so I could possibly transfer it over as an FBX file to Maya. I apologize if this seems a bit obvious of a question. Thanks for any help, Belt
  5. Hi, I'm trying to achieve this : I've got a footage of a moving hand. I've made a 3d hand matching the hand footage. Kind of 3d rotoscoping. Now I would like to use one frame (frame 30) to camera map the 3d hand with the frame 30 of the footage. I've manage to camera map the 3d hand, but at the moment it only match on frame 30. How could I "bake" that frame so that every frame use frame 30 for shading my 3d hand? I tried to use a REST POSITION node, but It's not helping, or I'm not using it properly ? Please let me know if I'm not clear enough.
  6. Hi, I've been trying for a while to render to UVs, but with no success. Rendering the constant shader to UVs works fine, but any other shader just fails (clay, stone, ect). Only the polygons that are seen by the camera get rendered, the rest is just black/shadowed. Any idea on why this is happening? Thanks in advance
  7. Hi, I know this topic has been broached many times before, and I did read all the posts, but I haven’t found a solution to the following problem yet: I want to bake light into the UV’s of a mesh. For that I’m using a point light and the UV render object option in the Mantra node. Basically, rendering it that way works, however, I have trouble with my camera. As soon as the camera’s perspective is only slightly altered, I get a different result, which (to me at least) makes no sense, because both the objects and the light stay the same, so the areas that receive light should also remain the same. Even those objects the camera can’t see have light baked onto them, but if I turn the camera towards them, the result is suddenly drastically different. The attached pictures show the difference: In pic 1, the camera is pointing towards the objects; in pic 2 it’s pointing away. I’ve also attached a test scene. Is there a way to render the entire 360° of the light, so the result always remains the same, the position of the camera notwithstanding? Unfortunately, Enable Hiding in the Mantra node didn’t solve this problem. I’ve also tried with the toNDC function and a rest position, but I didn’t get that to work either. I’d be very grateful if someone could help Cheers, Pascal projectionProblem.hip
  8. hi there. I´m doing some camera projection. I already did my camera matching, and now I want to project some parts of the image over the UVs of the object, so I add a UV Texture SOP, with the option "Perspective from camera". Now, as I want to retouch and fix some of those projected textures, I would need to bake those projections over ANOTHER UV. So, how do I do this? Do I use the "UV Render Object" on a Mantra node? How do I tell it to use another UV Mapping to bake the camera-projected UVs on? I´m sure many people has solved this before...
