  1. Hi family i have a geometry that went through a simulation, now in sops i have point position data, how is it possible to export an array of the position data across all frames of a desired point?
  2. Hello everyone, I've been getting into DOPs recently and i just cant figure out something. I have a SmokeObject and an RBD object. They are both plugged into the Pyro solver. The smoke has a collision relationship with the RBD object, and the Pyro solver's option "Temperature Merge" is set to "Collision Interior". In order for the "Temperature Merge" to happen the RBD object has to have a temperature field. Now what i want is for the RBD object's temperature field is to be just like what the smoke's temperature is but subtracted by a number so that the RBD object is always cooling the smoke. I've Created a fog volume that consists only of value 1 voxels inside the RBD Object and value 0 voxels outside of the RBD Object. I'm planning on using this as a mask for the smoke's temperature field (multiplying these two fields) and then lowering the value for all the kept voxels. Now i don't know what is the best way of achieving this but i thought that I can bring in the mask field (the only 1 or 0 field) into the dop network using the "Sop Scalar Field Node" and then extract the temperature field out of the SmokeObject using the "Fetch Data Node", wiring these two into the "Gas Calculate Node" and then blending and doing post subtraction in there. I don't even know if that is the right way to do it, but anyway once I connect the scalar field (the temperature mask, brought in from sops) into the gas node everything is ok. Once i plug in the data (SmokeObject's temperature field) into the gas node it reports an error saying that the connection to the fetchdata node is the wrong type. How could this be? Both the "SopScalarField" and the "FetchData" nodes output data, how come that the gas calculate will accept data coming from the "SopScalarField" node and not from the "FetchData" node ? I've been trying to resolve this for a while now, if anyone could help out it would be greatly appreciated
  3. adding metadata to exr

    Hey there, first odforce post and of course a question. i am currently looking for an option to add costum meta data to my render output (exr file). to be more specifiy, i want to save the focal length of my render cam to the meta data of my exr to read them later on in nuke. all ready found a way to put it in the comments, but would be cleaner to have it as costume data. i even found the vm_image_exr_attributes, but it seems like its not working (or i am using it wrong). would be great to get some help. cheers
  4. I'm trying to get attributes from a volume and group them by whatever data type they are. I was able to get the float type attributes imported, but I'm having difficulties with the vector types. My plan was to use the attribsize function to separate the attributes per type, but I believe that my code at the moment isn't looking in the right place. int attribType = attribsize(0,"prim",attributes); printf("Attrib %s = %s\n", attributes, attribType); If you have any ideas or solutions it'll be highly appreciated. Thanks!
  5. Hi all, I have been using the Pipe In chop and recording it with the Record Chop. I am now trying to save the data as a '.bclip' by right clicking the record chop then, save data channels. I get to choose the location, name and type. But when I click accept is says 'save failed: unknown reason'. I have tried all the different formats and saving it from chops further down the line. Also switching on and off the export flag. Has anyone had a similar problem? Is it a licensing thing? Any help would be appreciated. Thanks.
  6. How can I make "detail" or "global" data in dop? (like detail attribute in sop) Can it only attached to objects? I can do work without it. But just curious. Thank you~
