Clouds issues

[de-Roo.Lukas]

Sometimes when I launch the program, the clouds are often changed to some strips. And I when restarted it, it normally will be normal again. Just want to know what will cause this problem and how to avoid it thanks.

Hi Lukas,

I'd like to get more info on this:

• how often does this happen? Every time you start the application?
• are you using geodetic pivot, is it a "parent" for CloudLayer?
• What API is this? DX or OpenGL?

I will try to reproduce this by myself but test scene will make it faster.

Thanks!

I reminds me this bug: https://developer.unigine.com/forum/topic/4781-random-terrain-decal-artefact/  Cant be somehow connected?

Hi Morbid

It happens quite often but randomly

The cloud layer doesn't have a parent

but one issue is that we change the density and speed of the cloud by reading an XML file constantly.

and we are now using DX

Does this mean that you're changing in runtime clouds .mat file?

And one more question, which SDK version is this?

Yep, the behaviour is similar, but this is different bug due to the nature of CloudLayer.

SDK version is 2.6.0.1

I used a track to change the clouds_base_0 material's coverage_contrast 

and I read the track value (cloudsvalue) through an xml file

    Engine::get()->runWorldFunction(Variable("TrackerWrapper::load"), Variable("oil_refinery/tracks/clouds.track"));

    Engine::get()->runWorldFunction(Variable("TrackerWrapper::blend"), Variable(3), Variable(cloudsvalue), Variable(1.0));

Hi Lukas,

Maybe sometimes there are some bad values come out of XML? Is there any way to check a minimal test sample with the material, XML and code?

Thank you!
