AlphaJoe Posted September 20, 2016 Share Posted September 20, 2016 So, I feel like I am going all the way back to 3D 101 here, but I am stumped. I normally do not model in Houdini, but I find myself in the situation where I am having to do some scene reconstruction from tracked data. The tracked scene is coming from Syntheyes and it generates a Null for each tracked point. I need to snap to these nulls to create the various assets required for the shot, however, I cannot seem to snap to the Nulls like I do when I snap to a Locator in Maya. I have seen some related posts regarding rigging and trying to snap bones to Nulls, and I think this is related. Can you really not snap to a Null in 15.5?

michael Posted September 20, 2016 Share Posted September 20, 2016 create an environment variable to turn off Fast Bones: HOUDINI_OGL_FAST_BONES = 0 see https://www.sidefx.com/docs/houdini15.5/basics/config_env - waaaay down at the bottom "When enabled, nulls and bones rendering is done by accumulating all the objects and issuing one instanced drawing call." what this means is that the bones and nulls in your /viewport/ are actually just instances of the first bone or null - which means they are super fast even when there are tons of them - we're actively addressing the lack of snapping (and other associated issues). 1 Quote Link to comment Share on other sites More sharing options...
