  1. If the falloffs are linear or spherical you could use 3d gradient shader. In this example simple Xpresso ties position of the null to the start of the spherical gradient, giving visual feedback how the gradient actually goes.. example
  2. If your animation is based on transformation parameters like PSR they can be wired in XPresso relatively easily. Spline modifier in Range Mapper node can be used to create offset in animation. example
  3. It can be done with XPresso. Couple things to be aware of: Sample node is to be used for sampling Effectors Strength, Always handy Range Mapper node can be used to change limits of values coming from source parameter to output parameter, RGB colour in C4D are interpreted as percentage or 0-100 rather then 0-255, but that can be calculated bu XPresso aswell. example
  4. Actually percentage of the Align To Spline tag has very little to do with real length of the spline unless interpolation is set to uniform. In any other case percentage is taken based on number of points, so.. in your example first cusp equals 25% and second one is 50% . Yeah..I was shocked too.. In case you needed to set interpolation of your spline to uniform, you can use offset in the Xpresso spline node. It ignores interpolation set on a spline as long as you keep Use Uniform Distribution unchecked.
  5. You have Separate alpha option checked..this means that C4D renders two files: RGB image named "paper" without alpha embedded and "A_paper" which is black and white matte that can be used as Luma Mate in AE - if I remember correctly.. ( I've been using BMD Fusion) If you want alpha embedded in your render turn Separate alpha off. That works perfectly fine in Fusion..
  6. Hi. Try to get texture files out of the folder and place them on the same level as fbx file.
  7. Hi, This is a classic example of wrongly oriented bend deformer. Deformation always goes along Y axis so you need to rotate it accordingly.
  8. Go to Sweep object Object Tab and chenge rotation of the sweep..
  9. I know it's bit a late response but maybe still will be of some use. To split stream of particles, you could use a Birth Number as a custom particles channel. Then using math node in modulo set to 2, you can send every second particle to a different group. Remember to set the condition node data type to Link and drop the names of your particle groups there.
  10. Not an expert in Italian so hard to fully understand your XPresso setup i think you need to put Solid Layer in Sound Effector Fallof to sample it correctly..
  11. You could use tracer for this.. Go to Attribute manager and under Mode =>Project info you can get access to the length of the spline. Create cloner in object mode and set required amount of clones. Uncheck Loop !! (I have clones every 10 units for better clarity.) Create Tracer object and set tracing mode to Connect All Objects Create copy of the tracer using Current state to object. Hope that helps.
  12. This is an old plugin based on COFFEE i believe, so you would need special bridge files from Insydium. But even that doesn't help in many cases..
  13. Bitmap node can read rgb/grey scale value of a pixel at given x,y position of an image..
  14. I think particles need to be assigned to specific group right after they are born to avoid confusion. Also you need to change names of those groups in each Xpresso tag..
  15. Hmm, I'm not sure why it is not working for you.. Anyway, here is a scene for you. It makes use of c4d shaders - no textures, so I wouldn't have to upload them. Check that out. Remember that if you are using other effectors to alter position, scale etc. , you might want to turn Color Mode off in those.. hope that helps, Wojtek multi color.c4d
