thanks for fixing. I wanted to take a look at this several times already, but never managed to actually do it

Glad to help.

Looking into this issue I came upon these options:

-O puqs    = Optimize vertex buffers for shaders.
             p converts POSITION to 16-bit floats
             q converts normal tangent and bitangent (28-36 bytes) to QTangents (8 bytes).
             u converts UVs to 16-bit floats.
             s make shadow mapping passes have their own optimized buffers. Overrides existing ones if any.
             S strips the buffers for shadow mapping (consumes less space and memory).

Is there something equivalent for OGRE v1?

Could this be ported to OgreXMLConverter?

Looking into this issue I came upon these options:

• pu these have very only a very narrow use-case, as float16 only gives you 1024 different values. i.e. limits you to max 1024x1024 textures or an according volume for positions.
• sS this is not applicable to Ogre1. Also, I dont think you gain much by using them.
• q: there is -pack for Ogre1, that does something similar https://www.patreon.com/posts/vet-int-10-10-10-65546177 It also brings down storage of normals from 12 byte to 4 byte.

Could this be ported to OgreXMLConverter?

actually, similar options were kicked out of OgreXMLConverter after 1.9, to ensure it always does a 1:1 conversion between binary and XML. E.g. -pack and float16 conversion are lossy operations that store a different value then what you started with in XML
