There is only one sample taken for the whole object, even if it is a large particle system. Only one lighting sample is interpolated, at the center of the object's bounds. Translucent materials receive diffuse GI from the Indirect Lighting Cache. Light functions are also taken into account. Shadowed direct lighting from all movable light types is injected into the translucency lighting volume. Raising this increases lighting volume coverage but reduces effective resolution. R.TranslucencyLightingVolumeOuterDistance, which defaults to 5000. R.TranslucencyLightingVolumeInnerDistance, which defaults to 1500. Raising this by a factor of 2 increases the cost to light volume by a factor of 8.

R.TranslucencyLightingVolumeDim, which defaults to 64. The volume is configured through cvars that can be set differently based on the scalability level: This allows lighting to be known in a single forward pass for any point inside the volumes, but has the downside that the volume texture is fairly low resolution, and can only cover a limited depth range from the viewer.

Lit translucency gets most of its lighting through a series of cascaded volume textures oriented around the view frustum. Different lighting techniques are needed for each of these, so a material must specify the Translucency Lighting Mode that should be used.

Grayscale tones between black and white will result in more or less transparency in Lumion:ġ.3: Once you've added the Transparency mask to the Alpha Channel of the texture, please click on the link below to see how to save it to a 32-bit Color Map texture in TGA, BMP or TIFF format. There are 255 levels ranging from pure black (fully transparent) to pure white (fully opaque). The amount of transparency depends on how bright the pixels are in the Alpha Channel.

Making some parts of a material more or less transparent.

The Alpha Channel can be used for 3 different purposes in Lumion: In addition to the red, green and blue channel, you can add a so-called Alpha Channel to the texture if you've got Adobe Photoshop, GIMP or a similar image editor. You will need a special Color Map texture with an Alpha Channel in order to make some parts of a Standard Material more transparent than others.Ī Color Map (Diffuse) texture has normally got 3 channels: red, green and blue.
