I'm using java3d 1.3 beta1.
I have hit some bug when updating many nodes. By my mistake, on button change, same textures in textureunitstates were enabled and disabled few times (to be exact, enable,enable,disable,disable,disable). This killed renderer with following error java.lang.NullPointerException at javax.media.j3d.RenderBin.updateObject(RenderBin.java:546) at javax.media.j3d.MasterControl.updateMirrorObjects(MasterControl.java: 2565) at javax.media.j3d.MasterControl.runMonitor(MasterControl.java:3230) at javax.media.j3d.MasterControl.doWork(MasterControl.java:2817) at javax.media.j3d.MasterControlThread.run(MasterControlThread.java:28) I don't know if it helps, but TextureUnitStates were as follows on some shapes [0] - SPHERE_MAP, MODULATE, RGB [1] - explicit texcoords (TexCoordGeneration set, but disabled), DECAL, RGBA and on other shapes [0] - null [1] - explicit texcoords (TexCoordGeneration set, but disabled), DECAL, RGB BTW, if we are subject, in second case, will using REPLACE be faster than DECAL for non-alpha texture ? It should look the same, I just wonder if there is any gain here. Last time info - even when I fixed my bug, I'm able to reproduce similar thing on one of models (but rest works ok). java.lang.NullPointerException at javax.media.j3d.AttributeBin.reInsertTextureBin(AttributeBin.java:285 ) at javax.media.j3d.RenderBin.updateObject(RenderBin.java:546) at javax.media.j3d.MasterControl.updateMirrorObjects(MasterControl.java: 2565) at javax.media.j3d.MasterControl.runMonitor(MasterControl.java:3230) at javax.media.j3d.MasterControl.doWork(MasterControl.java:2817) at javax.media.j3d.MasterControlThread.run(MasterControlThread.java:28) Replacing [0] on some shapes from null to (SPHERE_MAP, MODULATE, RGB), even if it is not visible, fixes it (I cannot longer reproduce it). But I want to have ability to use only one stage of texturing, even if more unit states are allocated. I have to allocate more, because geometry is defined in this way - explicit texture coordinates are allocated to tus[1], so I have to put empty tus[0] there. It seems to be terrible waste for me to put some real texturing there, only to REPLACE-mode it later.
