Phoenix FD Maya Beta - problems

[alsh3lan]

Hi

some problems with the PlayBack , Clear simulation cache Interactive Rendering , rendering .

* the playback in the shelf not working ... but if i use the playback in simulation tab everyning is ok .
* the playback in the shelf just working if i do a simulation for one time from the simulation tab .

* if i stop the simulation from simulation tab and Clear the cache then start the simulation from the beginning everyning is ok , but if i use the playback in the shelf and pause the simulation and Clear the cache then start the simulation from the beginning the cache not updating in the scene .

* sometimes if i click the IPR Render and activate the v-ray Interactive Rendering During the process of simulation , the simulation suddenly stop and the grid stick with the shape of last simulation frame and nothing is updating (Clear cache , playback simulation (tab,shelf) ) .

* sometimes if i do rendering for the first time During the process of simulation it just render the the source (sphere, ... etc) .

If you mean by playback the "start/stop simulation" shelf button, you must select a simulator first. We can make it to pick automatically a simulator, but this may be confusing if you have more then one in the scene. Need to think about it.

Pause means that the simulation is just waiting, the start button wll resume it from where it was paused. You can use the start/stop button to really stop the simulation if it was started. In the nightlies, there is a Phoenix FD menu, which can "reset" the simulation for you - stop it, clear the cache and revert to the first frame. However this workflow is not particularly needed in Phoenix. You may just use that single button "start/stop simulation". The cache will be automatically overwritten.

We are still working on the IPR rendering. I will look into this issue. In beta2 IPR is not working at all. There will be some progress for beta3.

About the rendering during simulation, its supposed to work. Probably the next unsimulated frame is picked sometimes. I will investigate that too.

Hi ivaylo.ivanov
thanks for clarification

* another thing when i set the Adaptive Grid to Smoke after few frames the top of the smoke cut off
even when i set the Threshold to small value 0.05 , " is there a solution or some setting " .

[ivaylo.ivanov]

Hm, it's working for me. Can you send me the scene?

[alsh3lan]

i Sent the file to you

[ivaylo.ivanov]

It's working, but the settings do not match well. The simple smoke produces too much opacity, and levels bellow 0.05 are still visible, so it looks cut-off. You can do one of the following:
- decrease the simple smoke factor
- make a custom diagram to use only smoke above 0.05 (probably the best solution)
- decrease the threshold even further

thanks ivaylo.ivanov


* sometimes when simulate a simple flame and press the render button while simulation i get :
