I want move something use <Transform> and <Matrix4>

This is a nif file:

64af0977jw1e5ldpmwd9yj20pw0jitar.jpg690×520

This is a egg file that nif to:
64af0977jw1e5ldpltgbyj20ma0hhaau.jpg690×541

This is a egg file with and :
64af0977jw1e5ldpulmf3j20ma0hht9r.jpg690×541

The code than use to create :

def writeTransform(block, file_object, groupName=""):
	print("<Transform> { <Matrix4> {", file=file_object)
	print(1, 0, 0, block.translation.x, file=file_object)
	print(0, 1, 0, block.translation.y, file=file_object)
	print(0, 0, 1, block.translation.z, file=file_object)
	print("0 0 0 1 } }", file=file_object)

Matrices in the EGG is row-major

      <Matrix4> {
        1.000000 0.000000 0.000000 0.000000 
        0.000000 1.000000 0.000000 0.000000 
        0.000000 0.000000 1.000000 0.000000 
        X_value  Y_value  Z_value  1.000000 
      }

Okay, It’s my new code:

def writeTransform(block, file_object, groupName=""):
	print("  <Transform> {\n    <Matrix4> {", file=file_object)
	#print(1, 0, 0, block.translation.x, file=file_object)
	#print(0, 1, 0, block.translation.y, file=file_object)
	#print(0, 0, 1, block.translation.z, file=file_object)
	#print("0 0 0 1 } }", file=file_object)
	print("      ",1.0, 0.0, 0.0, 0.0, file=file_object)
	print("      ",0.0, 1.0, 0.0, 0.0, file=file_object)
	print("      ",0.0, 0.0, 1.0, 0.0, file=file_object)
	print("      ",block.translation.x, block.translation.y, block.translation.z, 1.0, "}\n  }", file=file_object)

and it’s egg file that create by nif2egg script:

<Group>  b'animNonAccum' {
  <Transform> {
    <Matrix4> {
       1.0 0.0 0.0 0.0
       0.0 1.0 0.0 0.0
       0.0 0.0 1.0 0.0
       0.0 18.5 7.199999809265137 1.0 }
  }
<VertexPool> b'animNonAccum'b'1'  { 

<Vertex> 0 { 23.905134201049805   -0.4957914352416992   0.19601762294769287

<VertexRef> { 45   41   59

  }
}
}
<Group>  b'body' {
  <Transform> {
    <Matrix4> {
       1.0 0.0 0.0 0.0
       0.0 1.0 0.0 0.0
       0.0 0.0 1.0 0.0

  }
<VertexPool> b'body'b'1'  { 

<Vertex> 0 { -35.9182014465332   17.969594955444336   -22.79993438720703

Effect is not different in pview.

I would really recommend that you use the EggData et al. classes in order to synthesise your egg file. That provides a much easier interface for you to generate your egg file, and prevents issues like these.

Well … I hope so, but panda3d supports noly python2 and nifformat supports noly python3. My nif2egg script need nifformat.

6

Are you sure that you used the same coordinate system in the both case?
Default is { Z-up }

Yes, I omitted it. It’s my complete file:

Aha, I see. Seems that is
