    To be honest, the HD morphs are a bit of a gimmick, the only thing they provide over other techniques, with the exception of vector normal maps, is that they allow for full or partial undercuts and creasing in the geometry, which is ok for extreme morphs and characters, but practically useless for general everyday human figures. For human figures you can do everything with standard morphs, displacement, bump, and normal maps. The only application I see for human figure HD morphs is in closeup animation because you can change morphs in animation easier than you can change images, but then people are not creating such content, they are creating HD static morphs for human figures, which is pointless IMO. If I want zits, scars and wrinkles on my figures, I get photoshop out.

     

     

    No you can't.

    Details from normal maps for example are lost at the outside.

    Just use tesselation maps then, those can change the silhouette of objects. I mean, you can do so with normal maps and some slightly fancy shader coding too if you like (though it doesn't look the best though as it's a bunch of "shells", and is pretty "heavy" as a shader).

    However, regardless, the point still stands that at even reasonable distances the effects on a "normal" human shape will be virtually indistinguishable. 

    Reasonable, by who's definition. Close ups, and characters often end up in closeups, will change what is 'reasonable'.

    The only substitute for geometry is geometry, anything else is getting around limitations of the system and about what compromises one is going to have to take.

    They can certainly be indistinguishable, but can means they can also be distinguishable too.

    Tesselation does use geometry, that's it's very purpose. The only difference is one is generated by a map. 

    Reasonable is going to be anything closer than extremely uncomfortable conversation range, and even noticeable then only probably if you're purposefully looking for it  (and it's not obscured by DoF or lighting or background contrast). Otherwise it's not really the type of thing a typical person would even notice. How many times have you looked at a photo of a person and gone "hmm, well, their silhouette is very, very slightly different than how it should be, there should be a slightly darker pixel near this wrinkle, totally ruins the picture".

    As a test, I overlayed the "non HD" pictures over the "HD" images for the characters in the store. The differences in silhouettes even in the extreme closeups were barely anything (and practically not there for most of the non old characters). You should try it too (just use a photo program, color one layer and set it to "difference", then look at the very edges).

    Just for clarification. The question has arisen many times in morph transfer discussions so, it appears transferring of HD morphs is desirable. Morphs are just better in HD. Alas, there appears no hope. I've scoured forums and the persisting answer (Up till June 2017) is that it's impossible. Why is this so? Must it necessarily be this way? 

    I don't understand why people can't take a few extra mionutes and create a completer Morph set from OBJ exports.  You export an FBX for skinning info,  a Base Obj and an Obj for whatevetr HD Morhps you want (I export at High Res at setting 3 its like a million faces!  (Actually I hide the body and export the Head and Neck only OBJS so only the Head has Morph Tragers not the whole body!) then you simply use a SKINNING Transfer topol like 'SkinWrap' in 3ds Max and give the relative skinning from the FBX Low Rez to the OBJ Base High Rez by vertex position,  (Works Great! Gives the NICE SMooth DAZ Skinning to the UE4 model!  Nice Joints etc.!) I use the UE4 Bones renaming Script to make the character UE4 friendly,.   I use Send to UE4 to get my Materials only basically,.   I use FBX for Skinning to xfer to the OBJs base and it's morphs,.Whats the problem???    I will upload a video if there is a need, I have about 3k subs maybe it will help them too,.  me:  youtube.com/NextWorldVR
