    Pulse emission not working as expected.

    Thanks, we'll look at this and hopefully fix it as soon as we can. Steve

    Thanks. Did you post a bug report? I haven't seen it on our bug tracker database yet. Steve

    Pulse emission not working as expected.

    Having looked at this, the problem seems to be due to tiny floating point errors in the calculation of timings in the emitter. If that's the case there isn't much we can do because it's inherent in the floating point unit of the CPU, but we're still looking at it. As a workaround, if you get this problem try increasing the subframe steps (project settings, X-Particles tab). Setting this to 2 or 3 seems to fix it in all the examples I've tried. Steve

    That's a bug, please post a bug report using the bug reporter in XP. Thanks. Steve

    OpenVDB Mesher not working

    I see you've already submitted a bug report but raise a support ticket as well through our website and they'll help you get it sorted. Steve

    OpenVDB Mesher not working

    See this FAQ on our website: https://insydium.ltd/support/faqs/?q=openvdb Try that and see if works correctly then. Steve

    Vary Motion Modifier over Lifetime?

    This is what data mapping is for. If you don’t have that in your version of XP you will need to upgrade. With data mapping you can vary turbulence strength by the particle age, or by some other parameter such as speed or radius. You have data mapping if the modifiers have a ‘Mapping’ tab in the UI.

    emitter only spawn

    This happens because although the kill modifier kills the pink particles outside the box, they live long enough to spawn from, so you see the green ones appearing outside the kill box. The easiest way to deal with this is to give the spawn modifier a box falloff, so spawning will only take place inside the falloff zone. If you resize the falloff to match the size of the box of the kill modifier it will work as (I think) you intended. The emitter option you refer to is from a previous edition of XP, it was changed quite a long time ago to 'Emission Mode' with an option for 'Controlled Only' which is what it is set to when you want to spawn from an emitter but not emit independently. It looks as if the docs were never updated to reflect that - sorry about the confusion. Steve

    Trails deformer

    Use a trail deformer, clear the formula fields then in the Shader tab add noise shaders to whichever axes you want to affect. You will probably want to set the mix values pretty low.

    mixing fluids help please

    The fluid collider tag is no longer required, use an ordinary collider tag instead. Steve

    must I need cycles to open files ?

    You can open the files, but if they use Cycles and you don't have that installed, Cinema will probably tell you there are missing objects in the scene. You can ignore that, delete all the Cycles mats, tags, and objects, then use the scene in Arnold. In other words, the absence of Cycles won't prevent any X-Particles objects in the scene from working, you just won't be able to render it without adapting it to your preferred render engine. Steve
  13. You have two copies of the R20 Bridge plugin installed - c4d_bridge.xdl64 and X-Particles.xdl64. Try deleting one of them (the c4d_bridge.xdl64 file). Then it should work. If it doesn't then you have another copy of XP installed elsewhere, probably in the user preferences folder for R20. As a side note, you seem to have installed XP into the /program files/maxon/cinema 4d r20/plugins folder. We strongly advise against this, as it may cause the online updater to fail due to the write protection Windows puts on the folders in /program files. Put it in the user prefs folder instead. There's more detail on this in our knowledge base, https://insydium.ltd/support/faqs/?q=install Steve

    Hardware requirements

    I'm sorry, I can't give you anything more I'm afraid. It's not possible to make hardware recommendations, there are simply too many variables - CPU speed, number of cores, amount and speed of RAM, and so on. And the hardware affects different parts of XP differently - whether more cores or higher CPU speeds are better will vary depending on what you are doing. We have a very wide variety of systems that we've tested and the only conclusion we can come to is that it's not possible for us to advise on hardware. That's why I emphasised this was a purely personal opinion and definitely not an Insydium recommendation.

    ThinkinG Particles tab

    Thinking Particles are not included in all versions of Cinema, so at a guess you are using something other than the Studio version. If so, there's nothing you can do (except upgrade to Studio). Steve
