#define / How to Identify 3DSMax version in Shader.

Anonymous — Tue, 17 Oct 2017 11:10:04 GMT

Hi,

Our shader for 3DSMax 2015 appear BackFace when we use it in 3DSMax 2018 (we want to upgrate to this version)

In order to support the 2 versions, we need a #define or something in the Shader to identify Max version.

Are you aware of a #define value we can test ?

Thanks,

FRED

Nobody knows ?

I don't know anything about Shaders, but I always use the #define MAX_VERSION_MAJOR to compile for the right max version.

Simple example with directives (used for NOTIFY_REF_CHANGED_ARGS):

#ifndef NOTIFY_REF_CHANGED_ARGS
#if MAX_RELEASE < 16900
#define NOTIFY_REF_CHANGED_ARGS Interval changeInt, RefTargetHandle hTarget, PartID& partID, RefMessage message
#else
#define NOTIFY_REF_CHANGED_ARGS const Interval &changeInt, RefTargetHandle hTarget, PartID& partID, RefMessage message, BOOL propagate
#endif // MAX_RELEASE
#endif // NOTIFY_REF_CHANGED_ARGS

Hi Siger & Istan,

Unfortunately those directives (MAX_VERSION_MAJOR or MAX_RELEASE) did not work in Shader Code.

I'm wondering if one directive exist to do that.

3DS max recompile the shader as soon as I change the code but is there any dynamic directive that contain the Max Version that launch that compilation ?

Still wondering...

is this what you seek?

#define VERSION_3DSMAX ((MAX_RELEASE<<16)+(MAX_API_NUM<<8)+MAX_SDK_REV)

take a look at plugapi.h in max sdk headers 🙂 all is there
