I present my collection of synthetic HDRI light textures - 'Flat' series

This time it is a square 'Softbox' - 1: 1 proportion, with an almost completely flat style.

It means that the lighting is homogeneous on almost the entire surface except for a small edge where the luminosity gradually falls (this is so because I personally do not like HDRIs with sharp cut edges and i always made it with a subtle smoothing in the contour)

The textures are able to illuminate a scene using it in the texture channel: luminance, self illumination, emission ... or whatever it is called in the program you use.

The example images are simple scenes illuminated only with a plane with the HDRI as a texture (in diffuse / albedo, in emission and in transparency) using Cycles as a render engine

• They come in 4 different flavors: Cold, Warm, Greenish and Neutral, the most basic tones when simulating any type of lighting (the 4 tones are included in the same compressed file).

They are soft tones like those that would be used in Photography when using filters or gels in the studio flashes.

• The images are 32-bit HDRI files with a Linear color space so they do not lose any shade of hue, and in .hdr and .exr format so that there are compatibile whatever the tool that you use

They have 4k resolution (4096 x 4096 pixels) and a small black border to not lose the gradient at the edges (this is more noticeable depending on the shape of the Softbox)

Format: .hdr (RADIANCE Image Format) / .exr (OpenEXR)Projection: planar UV / flat projectionResolution: 4096 x 4096 px (4k)Color Dept: 96 bit (32 bit per channel)Luminance: +-3 EV

NOTE: The sample scenes of the promotional images are NOT included, the compressed file ONLY CONTAINS the 8 HDRI textures (two formats for each of the 4 tones) and promotional images)
