Qt 3d studio does not support double side texture?

[small_bird]

Hello everyone, I have tried qt3dstudio, but it seems that qt 3d studio does not support double side texture. Is that right? Or I do not find the correct method, could anyone help me? Thanks in advance！

As you can see in the picture. Now I want to see the backward, how to do that?

[filipdns]

Hello, just in case, did you try to set the light upper?

[small_bird]

@filipdns Light upper? What that means? Put the light upon the object?

[filipdns]

yes, in studio, move the light on Z axe

[small_bird]

@filipdns

In the modo, it could show double side.

[filipdns]

It's just an idea, I'm not sure but on picture it seem like the light is on zero on Z and the model too

[small_bird]

@filipdns I have tried that, it doesnot work.The qt3dstudio seems too young, it needs growing up.

[filipdns]

yes may be

[filipdns]

I never use MODO but blender and in it, I have setting Backface Culling, if it's setting ON that hides the back side of each polygon, may be do you have it in modo?

[small_bird]

@filipdns I have tried blend before, however, it can not export object in the above picture. Could you do that? Or I have not found the right method?

[filipdns]

with blender the easyer way is to export the model in fbx. for the picture use the UV wrapping methode and include the picture as diffuse map in studio

@filipdns Thanks a lot, it works!!!

[filipdns]

great news !!

[filipdns]

Don't forget to switch this post as solved ;-)

[small_bird]

@filipdns In the blender, it is double sided option? I have checked that, but the result is still the same.

[filipdns]

send me this model I will check

[filipdns]

it's simple cylinder?

[small_bird]

@filipdns no,it is a cylinder without cover.

[small_bird]

@filipdns ok, I will send to you tomorrow,china is at night.

[filipdns]

that is what you are looking for?

[small_bird]

@filipdns yes,how could you do that?

[filipdns]

in blender you add cylinder as you want and with modifier tool you make very small thickness to have interior faces, an other modifier to triangulate all faces after you unwrapp it.

[small_bird]

@filipdns En, could you send me the fxb file? Thanks in advance!

@filipdns Now, it seems that the qml part can only import standard object in the studio, the holy cylinder showed above can not be imported.

[filipdns]

sorry I don't know what you mean, could you explain little bit more?

[small_bird]

@filipdns I mean that the fbx file you give me can not be loaded by qtstudio3d in qml.

You see that? The holeCylinder.uip can not be loaded by qml studio code, that's when I run the qml code, the window shows no content.However, the testSphere.uip can show normal, it is the qt3dstudio inner type.

[filipdns]

ah ok, yes, I 'm not using fbx like that, I create new studio project called "test" as example (not creator) then I drop fbx to model of this new project and save the project.

After that, create quick project with in the main.qml:

//
import QtQuick 2.6
import QtQuick.window 2.2
import QtStudio3D 1.0

Windows  {
visible: true
width: 1280
height: 1024
title: qsTr("test")

                Studio3D {
                 anchors.fill: parent
                 source:"<test project source directory>/test.uip"
        }
}

[small_bird]

@filipdns Yes, I also did that like you, however, the quick project can not show normally.

I mean that I'd like to change the texture dynamically, how to do that? This is the link https://forum.qt.io/topic/84700/how-to-change-diffuse-map-of-cylinder-in-studio3d-of-qml.

[filipdns]

what is not normally for you? it's working in studio viewer?

[small_bird]

@filipdns After I import the uip file into the qt quick project and click run button, the window shows no content.

[small_bird]

@filipdns I have sent you the uip file.

[filipdns]

I received and made qml project with it, it's working here, try it, I just sent to you

[small_bird]

@filipdns I have tried that, however, it does not work for me.

However, when I tried another uip file, it works there.

[filipdns]

Hi, I have the same issue sometimes, I think that is studio bugs.
To have working, I open the uip with studio and replace the mesh by the native mesh, compile again and open uip in studio again and replace mesh to the original and compile again, I don't know why, I ask help in this forum for the same problem.

@filipdns En, hope someone could solve the problem.
