Questions. SH5 models and dynamic shadows

[Rosomaha]

1. What is responsible for building dynamic shadows on GR2 in sh5? What parameter / setting or property? Someone had a successful editing - adding models with dynamic shadows?

2. What version of GR2EditorViewer is able to add new Bones to the GR2 file without errors, if any?

1 - IIRC, unlike other SH games SH5 dynamic shadows are automatically calculated when it comes to GR2 objects. I think they are encoded somewhere in the shaders. There is not controller / parameter / setting that I remember of.

2 - Try some of the older versions, I don't remember which one works for me, but I can send you all the versions I saved on my HD if you want

Hi, Gap. Thank yuo. No I do not want to. I have an entire carriage of these versions. I have been collecting material for a long time, unless ... not have SDK GR2EditorViewer from TDW?

It seems I understood: large objects up to a certain size have shadows, while small objects, such as "NF_Boat_1" and less, lose them. Perhaps for this reason, NF_Boat_1 is not included in the "Roster" of the stock game (although his model remained at "Sea" folder), the developers also did not add a "torpedo boat" to the game, there are no more shadows on "CMD_small_boat". Obviously, these are the settings for the game renderer for units, size does matter.)

I don't know what do you mean by SDK in this particular case, but I can share the version of granny viewer that TDW and Jeff (Grove aka privateer) used for hacking many secrets of the GR2 format

I don't know what is the problem with that boat, but in the past I have imported some custom units in game (as granny objects), and they do cast shadows. IIRC, unlike water reflections which require a secondary model, shadows are calculated based on 3d mesh is used. Your guess that unit size matters for shadow calculations could be correct, but the only way we can investigate on it is by looking in the game shaders

SDK - software development kit - source code of the program GR2EditorViewer.
if you about gr2-viewer of radgame – I have this thing in bulk too:



"NF_Boat_1" (added on Roster in The Wolves of Steel) I gave for example only. Gap, you personally can easily check this guess on this sh5unit even without going into the shaders - GR2EditorViewer-> Export obj-> in 3DsMax or other 3deditor - simply increase the model by x2 (enough) or more times -> GR2EditorViewer -> Import mesh back to GR2 and dynamic shadows appear on “NF_Boat_1”:

Okay, if you are talking about the source code of GR2 Editor/Viewer, I am afraid only TDW can provide it, and unfortunately he has not been around for a long time. Nonetheless, as I mentioned in one of my previous posts, another veteran forum member, Jeff Groves, might have some pieces of information for you. IIRC, TDW's work on his editor started with an exchange of information between him and Jeff.

8.2.33.0 is the version that I am talking about. Apparently, it has some "weak spots" that TDW was able to exploit for understading better the (then) new and still undisclosed 3D format.

Okay, since it is obviously that you have already confirmed your guess, I think there's no need for me to do the same.

My suggestion to look into the game shaders was more about the "why" size matters for shadow calculations rather than "if" it does or not
