Hi, I used Hex2obj getting rx2 models extracted. There is no option to set vertices in half-float and uv’s in word in hex2obj so it need to be extract separately. Here is short tutorial, hopefully it helps:
Open rx2 file in hex2obj (example is goaliepad_2.rx2).
Fill the fields like example image. Next step is important because UV’s and vertices isn’t same type and there is no option to set vertices in half-float and uv’s in word in hex2obj. So thats why you need to set type box to ”HF_all” and then click mesh. Test.obj will appear in same folder where the rx2 file is.
Then set vertices option box to ”WordUV” and click UVs-button and testUVs.obj will appear in same folder where the rx2 file is.
This is extra work and it must be done because there is no option to set vertices in half-float and uv’s in word in hex2obj.
You need to modify testUVs.obj in text editor (I use text wrangler in mac) and you need to select all ”v” letters and replace it to ”vt” and then select all and copy. Then open test.obj and go starting of faces and select all in end of file and paste uv’s here and save the file.
Now you can open .obj in blender and create textures with it in blender. Textures need to flip vertical in default but if you open UV editor in blender and flip uv’s there you don’t need flip images.
There is different types rx2-files in NHL for example puck and net files are float-types and head files contains more than one object.
Im not expert in models but hopefully that helps you.
