Please tell me the vegetation of this engine.

How to achieve this effect.

I can't make a constituency with PS. Such a precise constituency

[morbid]

Hello Zhu,

What exactly do you mean by "I can't make a constituency with PS. Such a precise constituency"?

If you're talking about padding effect visible on the albedo texture, it's usually made with XNormal plugin for Photoshop. It can be done in Substance Painter as well.

Thanks.

Hello, I want to make a snow map at present. There are mainly problems in the following aspects.

Snow example effect, not real enough.
I want him to cover things.

The snow on the ground looks too fake. How can I make snow on a map.

[zhu.jun]

What's the difference between sensor temperature and object temperature?

Snow accumulation can be made with a custom shader, such things are usually made considering project requirements.

You also can combine decals, meshes and SSDirt effect to simulate snow cover.

Can you be more specific? Object temperature is controlled by Thermal Map, Sensor visuals are defined by LUT texture. Principles are described in this article: https://developer.unigine.com/en/docs/2.9/content/materials/library/postprocess/post_sensor/

Thank you.

What's the difference between   Temperature of the object At   and    Sensor temperature T，

 

[morbid]

At is the temperature of the object, T is the temperature of the environment. Both variables are described in the article, what exactly is the problem?

I want the particle effect of snow to cover the soldiers. What should I do.

I want the soldiers to collide with the snow, or the soldiers and particle snow to stick together.

 

At the same time,When creating terrain, height, albedo, you can choose flat, TIF, JPG, PSD, DDS and other image formats.These pictures are of different formats and sizes（capacity）. How do I choose?

 

In the same picture, the TIF is 800 trillion, while the PNG is only two.

[zhu.jun]

is their unit the same as the real one?

Is the unit of at Celsius?

 scale ,

What's the ratio in unigine.

Proportion of mass, proportion of distance, proportion of temperature.

Their ratio to reality.

This can be done with a custom shader that will change the albedo texture of a snow-caped object. We do not provide such feature out-of-the-box since it can't be designed as a generic one. Such things are made per unique project.

Particles already support collision and interaction, but huge amount of particles will significantly drop performance.

No, heat maps and post effect are imitating sensor, they are not directly related to the real physical values of temperature. You can adjust a number of parameters to achieve desirable visual effect. If you can describe the task we'll give you a more precise answer.

Landscape Tool can handle any of these files. Just use the ones you have.

I believe all required methods are available in the Unigine::Material class. Before you start make sure that you have inherited the material. You can't edit standard ones.

Thank you.
