Why has my rendering completely changed from 2.7.1 to 2.7.2.1

[sebastian.vesenmayer]

Hi,

I managed it to migrate from 2.7.1 to 2.7.2.1.

It works so far when we are not using decals for most of our scene, but we recognized a significant change in the shading.

We did no changes to our Material initialization and textures, but the image is brigther and more saturated.

Why is this happening? Files attached.

Thanks

Hi Sebastian,

these screenshots are kinda small to tell what happened :) We did a bunch of render fixes but, as I already said, it's hard to guess what exactly went wrong.

Could you please send a simple scene on 2.7.1 with objects that will change after migration?

Thank you!

Hi morbid,

I can give you higher resolution images. Complete scenes are difficult because of a NDA with our customer.

This is 2.7.1:

This is 2.7.2:

Materials:

For aircraft:

<?xml version="1.0" encoding="utf-8"?>
<material version="2.7.2.2" name="BE30_NRS_blinn8" guid="fbaa27ae8e00f866917306c614043867908b52bb" base_material="mesh_base">
    <blend src="src_alpha" dest="one_minus_src_alpha"/>
    <options transparent="2" two_sided="1"/>
    <parameter name="material_mask">0x00000002</parameter>
    <parameter name="metalness">0.200000003</parameter>
    <parameter name="roughness">0</parameter>
    <parameter name="specular">1</parameter>
    <parameter name="microfiber">0.600000024</parameter>
</material>

For  all others:

<?xml version="1.0" encoding="utf-8"?>
<material version="2.7.2.2" name="database_RWY3_BLDG05_AnnexBldg_RWY3_BLDG05_AnnexBldg_mat" guid="2f1ac315d98dd2cdc1f05f13da6143ca604b60d3" base_material="mesh_base">
    <options transparent="1" two_sided="1"/>
    <parameter name="material_mask">0x00000001</parameter>
</material>

I will look for another example in future, but maybe it helps you for now.

Thanks

Thanks for the pictures, the issue now is obvious.

Can you send us a simplified scene on 2.7.1? For instance, primitives with materials, textures and render settings from the reference scene will be enough. We don't need the models.

I also suggest checking the following:

• If you're using Environment or Voxel Probes - try turning them off. Will it make the final picture closer to the old one?
• Try tweaking Light World parameters: color and intensity.
• Create a new project and save render settings. Apply them to the migrated project. Will it change the picture?
• Try changing environment and camera effects settings, will it help?

It's still hard to give you a proper advice, I'd like to see the scene.

Thank you!

Hi Sebastian,

any updates on the issue?
