    MATERIAL TO TRACER OBJECT

    any curve object needs a cyCurve tag to get rendered. does that help?

    How can I participate in the Early Access

    for EA program, https://insydium.ltd/products/early-access/ How to get your Early Access download. Simply change your existing Cycles 4D download link from: http://download.cycles4d.com/(your download ID) To http://earlyaccess.insydium.net/(your download ID) So, for example, if your download ID is 12345678, then the URL should be: http://earlyaccess.insydium.net/12345678 Once this is complete, you will be sent an automated mail from INSYDIUM for verification.

    Arnold

    you need to post this question in the right forums, https://community.insydium.online/index.php?/forum/9-explosiafx/

    NEW USER

    to render with alpha, activate transparent background from the render settings. to render with passes, activate multipass and add post effects, and activate whatever layer you want from Cycles 4D render elements

    Real-Time Preview Performance on iMac Pro

    Cycles core devs (Blender foundation) dropped the OpenCL support a few months ago for 2 reasons: Apple deprecated OpenCL, and the OpenCL driver on Apple is very bad and doesn't compile many parts of the code that works fine with CUDA and CPU and even on Windows OpenCL drivers, and Apple won't solve the problem.

    Real-Time Preview Performance on iMac Pro

    this was in the old UI (build 247), new UI is significantly faster (EA build 294) and it has this problem fixed even if that lag in the old UI was caused by Cinema4D native image conversion (internally calling OS blabla to convert colors on that system and screen). note though as you will use the Mac, OpenCL is deprecated and no longer supported. so getting nvidia is a must for GPU rendering.

    Background object

    what I mentioned does exactly that, the image should fit the window and fixed.
  8. Mohamed Sakr

    Background object

    add cyEnvironment, go to the background material, add input->texture coordinate node connect texture coordinate node->window output to image texture node uncheck load fro disk on the image texture node, check the flip Y axis, connect that to the background node.

    Display no colors in the viewport

    you are now using the demo build (which is the current release build 247), if you have the full build (non demo), you can access the EA build 294 which has the viewport colors applied. build 294 got many new features and faster node editor and RT preview. you won't need the viewport colors anyway in that build 🙂 you can also render in the RT and display the RT rendered image in the viewport (from the RT menu, there is a viewport checkbox).

    Matrix object

    thanks @dimitroleykin , note that if you modify the original matrix in the latter case you will need to do an event on the matrix object (like turning it off and on) to update its cache 🙂

    Matrix object

    @dimitroleykin thanks!, I see how you used a Cloner object to catch the data from the Matrix object, my fix wouldn't involve this 🙂 (if it worked at all)
  12. Mohamed Sakr

    Display no colors in the viewport

    in the EA build (294) it has viewport colors (except for textures as it requires sampling like image textures as it will slow down the RT).

    Matrix object

    may you post a scene please, I need to check what gives the correct result for such deformers
  14. Mohamed Sakr

    Matrix object

    thanks, we are working on a solution for the matrix object deformers as they don't generate actual (deformed matrices).
  15. Mohamed Sakr

    Matrix object

    please report a bug with the scene, we will have a look.

    rendering is different with the RT preview

    @mayasam you need to connect it to the volume socket so instead of the surface shaders (like diffuse BSDF and glossy BSDF), you need to connect it to volume BSDFs

    Planar Mapping Question

    Thanks, it was actually a bug in 247 🙂 as it ignored that tiling option. turning off tiling will give you in most cases the desired result. (which matches 247 result with or without the option).

    Planar Mapping Question

    please post a scene, which Cinema4D version?

    point light PROBLEM

    there is 1 more solution if you must use point object, if you don't subdivision in the editor, you can add a cyObject tag and do subdivision with catmull clark , this will do subdivision base on camera (aka micropoly subdivision).
  20. Mohamed Sakr

    point light PROBLEM

    @xpez this is known as shadow stepping, it is not a bug but happens because Cycles doesn't use any approximations for ray triangle intersections (for example in other render engines they use a ray epsilon of 0.001 to solve such problems). the solution for point light: increase the radius (which will give you softer shadows like area light), otherwise if you must use a point light without a large radius, mesh must be dense. in reality there is no point light, and Cycles is unbiased and doesn't use such approximations. making cyLight size to 50 or 100 cm solves this. for best lighting, I recommend using surface objects with emission materials.

    Dont render smoke and fire in v1.0294

    it is because the data isn't fully sent (these textures are sampled, sampling takes time), if any event is called during sending, it will cut the sampling and send whatever is already done, so it will appear cropped, volume textures takes time to sample, I can't hold the RT for 1 or 2 seconds till it samples the full texture (sending cropped is better than getting a full Cinema4D block for 1 second every update)., we are trying to find a better solution but it is more like a limitation with sampling large textures. we are working on a solution for this.

    loop animated textures

    you may need to animate the texture used frame manually instead of using c4d loop options
  23. Mohamed Sakr

    Dont render smoke and fire in v1.0294

    if at any point the texture didn't appear as expected (aka cropped), do a resend (change device from CPU to CUDA or from CUDA to CPU).

    Dont render smoke and fire in v1.0294

    The file you posted renders fine here, does it render in your case? which OS and Cinema4D version?
  25. Mohamed Sakr

    Dont render smoke and fire in v1.0294

    please post a scene.
