Create shared tentacle model.

[malortie]

Tentacle has no HD variant.

LD HL1 tentacle2.mdl <-> LD Op4 tentacle2.mdl

• same skeleton
• same hitboxes
• same attachments
• same sequences and fps, but level 1,2,3 sequences altitude is different in Op4
• same mesh
• same textures

LD HL1 tentacle2.mdl <-> LD Op4 tentacle3.mdl

• same hitboxes
• same attachments
• same sequences and fps, but level 1,2,3 sequences altitude is different in Op4
• same mesh
• same textures

LD HL1 tentacle2.mdl <-> LD Blue Shift tentacle2.mdl

• Identical

---

• Create default tentacle2.mdl
• Create tentacle2_lower.mdl with Op4 sequences that have different altitude

Additional information

1 - Op4 includes a custom tentacle model 'tentacle3.mdl', which is a slight variation of tentacle2.mdl but with different altitude for level 1,2,3 sequences.

2 - The Op4 tentacle2.mdl Level 1,2,3 root bone is positioned at a different altitude, making the sequences incompatible with the HL1.

3 - The Op4 tentacle has an additional spawnflag 64 'tentacle3' set and the original game DLL contains a string 'tentacle3.mdl', which leads me to believe that a specific model is picked whether or not this spawnflag is set.

4 - HL1 identical sequences have been reused when possible. I tested in game with the custom tentacle2_lower.mdl as tentacle2.mdl and haven't found issues with the sequences.

@SamVanheer

Please, can you review the following models in Release v0.4.0-rc.1 and confirm if the issue can be closed ?

• models/tentacle2.mdl
• models/tentacle2_lower.mdl

Important - Make sure to read section Map changes in the first post.

The models look good, and i've added an upgrade action to modify tentacles that have the spawnflag set to use the alternate model.
