no texture update HtoA

[hsafaei.it2008]

selection-021.pngselection-022.pngselection-023.pnghi, i use houdini 16 in Fedora26. when i connect an image node to diffuse color of standard shader as texture no change occur or sometimes Houdini close itself suddenly or sometimes the render image shows a static image without update. also when i try to update TX textures it says that textures skipped for my case it shows: 1 skipped.

i don't know how could i resolve this problem

What do you mean "no change occur" ? Do you mean the Render View does not update? What if you Render Frame to mplay, does that show the texture?

A tx won't be updated if nothing has changed.

If you insert a node while the render window is open, then it does not automatically update the way it does in c4dtoa. Only when you change parameters and attributes. I am not sure if it's supposed to or not.

[Stephen.Blair]

Connecting image nodes isn't supported yet (for IPR updates). That will probably be in the next phase of IPR improvements, which started with 2.1.1

[hsafaei.it2008]

in Houdini and Maya if you add remove or change any parameter you would see the render view update immediately , for my case i Use refresh button but no change happens and texture isn't applied to sphere or any other object. 😉

first tnx to your answer. [What do you mean "no change occur" ? Do you mean the Render View does not update?] yes i mean that, excuse me for my poor English.

[That will probably be in the next phase of IPR improvements, which started with 2.1.1] : Are you Sure?

i use version 2.1.4 :

bout [Connecting image nodes isn't supported yet (for IPR updates).] : i fallowed exact the tutorials and it is clearly possible as you can see in image here I've taken from a tutorial by Rohan Dalvi:

i used the same texture as you can see but my object don't get updated :

hi body. [If you insert a node while the render window is open, then it does not automatically update the way it does in c4dtoa. Only when you change parameters and attributes. I am not sure if it's supposed to or not.]:

in Houdini and Maya you can see render view get updated immediately if you change any parameter of objects or shaders also Add or Remove any shader node.....

i don't know about C4D verion of Arnold.

[Stephen.Blair]

IPR improvements are an ongoing process. Support for things like new image nodes inserted in a shader tree will come in a future update of HtoA.

[hsafaei.it2008]

so what about image above so how he could do it? do you think i couldn't fallow a simple tutorial?

i don't know what is IPR because i've decided to migrate from maya to houdini recently.

is it interactive physically Renderer?

tnx to your reply

[hsafaei.it2008]

may i ask you [Stephen Blair] have a look to this tutorial?

[hsafaei.it2008]

tnx again but i know you didnt get my mean.

[Stephen.Blair]

Adding a new image node and connecting it in the shader tree won't automatically update the Render View. You have to click Render and force HtoA to re-export the scene.

[hsafaei.it2008]

lets give up the render view and IPR. here is my final render image below:

you see that texture isn't applied to the sphere. so if you think i made some mistakes. plz give the correct tips and steps to assign texture to Diffuse Color of Standard shader then apply it to Sphere.

tnx

i did it many time but nothing happens about texture. is it depends on my CPU? i have a bugy Ryzen 1700.

Upload a scene file with the textures. Linking an Image to the Base Color of a Standard Shader is all you have to do, so there must be something else going on. Did you check the Arnold log for errors or warnings?

[frederic.servant · Accepted solution]

Does this sphere have UVs? Can you share a simple scene?

[hsafaei.it2008]

it didnt. i'm sorry for may late answer.

the objects didnt have UV. so after UV project the texture applied.

tnx

[hsafaei.it2008]

thank you while i found the problem myself 😄 😉

Thank you Stephen for your Patience.
