Allocates a temporary render texture with the specified width, height, format, and flags. This function can be used when you need a quick render texture to perform some temporary calculations. Release it using releaseTemporaryTexture() as soon as you're done with it, so another call can start reusing it, if necessary. In any case, such texture shall be released automatically in the next frame.
UNIGINE keeps an internal pool of temporary render textures, so a call to this method most often just returns an already created one (if the size and format match). These temporary textures are actually destroyed when they aren't used for a couple of frames.
If you are doing a series of post-processing "blits", it's best for performance to get and release a temporary render texture for each blit, instead of getting one or two render textures upfront and reusing them.
Notice
You can't depend on any particular contents of a temporary texture obtained from this function: it might be garbage, or it might be cleared to some color, depending on the platform.
It also automatically gives names to resources, which can be used for identification in debug.
Arguments

float engine.render.getLandscapeTerrainTexelSize ( ) #
Returns the texel size of the Landscape Terrain render textures representing the maximum level of detail for the albedo, normal, and height components of the Landscape Terrain.Return value
Landscape Terrain texel size (in meters), in the [0.0001f, 1.0f] range. The default value is 0.001f.void engine.render.setLandscapeCacheCPUSize ( int size ) #
Sets the CPU cache size to be used for landscape terrain rendering. CPU cache size affects intersections, physics, streaming, etc. The size of CPU cache depends on the scene.Arguments
- int size - New СPU cache size to be set, in percentage of the total СPU memory. The default value is 10%.
int engine.render.getLandscapeCacheCPUSize ( ) #
Returns the current СPU cache size used for landscape terrain rendering. CPU cache size affects intersections, physics, streaming, etc. The size of CPU cache depends on the scene.Return value
Current CPU cache size, in percentage of the total GPU memory. The default value is 10%.void engine.render.setLandscapeCacheGPUSize ( int size ) #
Sets the GPU cache size to be used for landscape terrain rendering. GPU cache is used to accumulate tiles, that are visible to the camera, before streaming them to the megatexture.Notice
High-resolution maps require larger cache capacity.
Arguments
- int size - New GPU cache size to be set, in percentage of the total GPU memory. The default value is 4%.
int engine.render.getLandscapeCacheGPUSize ( ) #
Returns the current GPU cache size used for landscape terrain rendering. GPU cache is used to accumulate tiles, that are visible to the camera, before streaming them to the megatexture.Notice
High-resolution maps require larger cache capacity.
Return value
Current GPU cache size, in percentage of the total GPU memory. The default value is 4%.void engine.render.setLandscapeCacheGPULifeTime ( int time ) #
Sets the lifetime of GPU cache used for landscape terrain rendering.Arguments
- int time - New GPU cache lifetime to be set, number of frames in the [1; 60] range. The default value is 4.
int engine.render.getLandscapeCacheGPULifeTime ( ) #
Returns the current lifetime of GPU cache used for landscape terrain rendering.Return value
Current GPU cache lifetime, number of frames in the [1; 60] range. The default value is 4.void engine.render.setLandscapeCacheGPUUpdateLimit ( float limit ) #
Sets the maximum update limit for GPU cache used for landscape terrain rendering. Lower values may help reducing spikes, but be careful, as setting too low values may result in growing cache size due to slower unloading of textures.Arguments
- float limit - New GPU cache update limit to be set, in milliseconds. The default value is 1.5 ms.
float engine.render.getLandscapeCacheGPUUpdateLimit ( ) #
Returns the current maximum update limit for GPU cache used for landscape terrain rendering. Lower values may help reducing spikes, but be careful, as setting too low values may result in growing cache size due to slower unloading of textures.Return value
Current GPU cache update limit, in milliseconds. The default value is 1.5 ms.Last update:
