RealFlow Renderkit won't render mesh in IPR but F9 is fine

[atnreg]

Hi!

I am just learning RealFlow 2014 and its Renderkit and it seems to be working fine except in IPR

When I set up the scene and hit F9, the fluid mesh renders fine but when I try that in IPR, the fluid mesh does not appear, everything else renders fine.

I know RealFlow Renderkit is rendertime plugin but as it works in F9, shouldn't it work in IPR as well, in Octane they are pretty much the same?
And it even works in LW's VPR so...

And the fluid mesh in each frame (i.e. IPR) is static so it would need to created once, then as long as the IPR is open, it would be used until something changes of course that needs it to be rebuilt. It of course need time at first but then it should work in IPR like everything else

I really hope I am just doing something wrong or if this is a bug it is fixable

Thanks!

I am not sure how RealFlow works inside the Layout. Can you see the fluid mesh in the OpenGL viewport? ... the IPR only can render the geometry loaded in Layout if it is available out of the rendering stage. It is clear that the RealFlow plugin build the mesh at render time for the F9 render, but I am not sure if the mesh is available always.

Anyway I think that you don't need a RealFlow license to read and render the realflow files, so if you want to send me a sample scene with the plugin needed to read the realflow files, I could test it here.

Thank you for VERY fast reply, wow

There is option Show mesh that shows the mesh also in OpenGL but it does not affect IPR (nor F9).
I made a sample scene with minimal data (one frame of fluid data, no other objects) and readme.txt inside for instructions.
Please extract the rar to c:\ to get the paths correct (more in readme).

Thank you very much for your time again!

EDIT: replaced the broken test scene with working one

Your readme file is empty

I am testing your scene, and I can see that out of the render context the object doesn't have any polygon. You can see it in the OpenGL viewports because it has a custom object plugin to draw the fluid in the viewport, but the mesh is not loaded in the Layout until you press F9.

Are you sure that you can see the fluid with the LW native VPR? ... here it doesn't work, it has the same problem than the Octane IPR.

Anyway your scene asks for an object RFRK_Mesher.lwo that I don't have. Perhaps the RF plugin could write the mesh to a temp file and later load it in the Layout to render it with the VPR.

Anybody else has experience with RealFlow and Octane?

I am in contact with an Octane and RealFlow user with a lot of experience with both plugins. We are testing some things about the Octane IPR and the LW VPR. I will post more information as soon as possible

Some facts about render realflow meshes with Octane:

* There are two procedures to load the realflow mesh in the Layout: RF Renderkit and Conectivity (or Manager). There's 2 downloads you get for Realflow. You have the renderkit, and then you have the connectivity plugins. I'm not really that well versed on the differences between the two; a lot of their functionality seems to overlap.
RF Renderkit ---> VPR does not work.
Connectivity plugin ---> VPR does work.



* To render the scene, or to see the animation in the IPR, you need to enable always the full scene reload mode. The RF mesh can't be updated.

* The only way to render motion blur with the RF data is to use the multipass MB with the option to reload the scene for each pass enabled. It is not fast, but at least it works.

I hope this helps.

I reply here to all those messages

Oh no, I did test the scene but of course I had the full scene so I thought it would work
But the empty readme I cannot understand, on my system (outside the rar) it is fine
I am VERY sorry for this rather unsuccessful demo that was supposed to be easy for you, fortunately you are pro so you figured it out anyway

And I think I was wrong, VPR actually did not work at all, the title said VPR but the view was still OpenGL

Also thank you VERY much for the further messages, as I told you I am just learning both RealFlow and Renderkit but I didn't think I was in THAT beginning. The documentation for RealFlow is - nicely said - not the best possible but now I see I really need to read everything about it before even trying, sorry to waste your time with missing instructions and not doing the RTFM with RealFlow Renderkit first

Now I will try to learn everything before making stupid questions

Thank you VERY much again for all your help on this, and even so fast! You are amazing

Just in case here is the fixed test scene.
