No Materials in the SOP for HtoA 3.3.0 for 17.5

[sfshook22]

I have updated to the latest release for 17.5 and everything seem to work except for the textures i.e. Standard Surface.

Thank you,

Steve

work like a charm here, Do you have the correct path in Houdini.env file?

Here are the env file settings (I changed them absolute reference):

PATH = "$PATH;C:\Users\Steven\htoa\htoa-3.3.0_rf4b10e6_houdini-17.5.173\htoa-3.3.0_rf4b10e6_houdini-17.5.173\scripts\bin" HOUDINI_PATH = "C:\Users\Steven\htoa\htoa-3.3.0_rf4b10e6_houdini-17.5.173\htoa-3.3.0_rf4b10e6_houdini-17.5.173;&"

I noticed that there was a missing ";":

@Steven Shook
Had this problem today and found that the Game Development Toolset variable somehow conflicts with the Arnold variables. So, just by moving this Game Development Toolset variable and placing it before Arnold variables, I was able to get rid of this conflict.

Don;t know anything about the technical part of it, but now it works fine.

Hope this helps.

In the console I get very different results then before:

Hi,

I am not able to render to render view or to Mplay (ip), but now do get the shadier graph nodes.

I have attached the log of the results.

Thank you,

I did read you notes above about the Games Devleoment Tools and the config information. I then copied and pasted that information in to the env file. I then sent you the my results just before you last answer.

I now copied and pasted your last env statements above into the env file and now I get this. Also the missing shader material nodes problem is back again.

You are incorrect about reading yours as I did read it, but saw the one after it from Vital Skib and used that one. Sorry my mistake. Not sure is who and who is representing Arnold for the answers.

Ok
make it simple

For GameDevToolset
1- create an empty houdini.env file in C:/Users/Steven/Documents/houdini17.5
2- create a folder "GameDevToolset" in C:/Users/Steven/Documents/houdini17.5
3- Cut what inside GameDevToolset/17.5/1.131 and put all the files in "GameDevToolset"
4- remove SideFX in %APPDATA

For Redshift
1- Create a folder "Redshift" in C:/Users/Steven/Documents/houdini17.5
2- Copy/Paste all the files from C:\ProgramData\Redshift\Plugins\Houdini\17.5.173 to Redshift you just created

Here is the HtoA path (again this "/" and this "\" are different !)
PATH = "$PATH;C:/Users/Steven/htoa/htoa-3.3.0_rf4b10e6_houdini-17.5.173/htoa-3.3.0_rf4b10e6_houdini-${HOUDINI_VERSION}/scripts/bin;"

add redshift path, to the existing path
PATH = "$PATH;C:/Users/Steven/htoa/htoa-3.3.0_rf4b10e6_houdini-17.5.173/htoa-3.3.0_rf4b10e6_houdini-${HOUDINI_VERSION}/scripts/bin;;C:/ProgramData/Redshift/bin"

add GameDevToolset to the existing path
Final Path

PATH = "$PATH;C:/Users/Steven/htoa/htoa-3.3.0_rf4b10e6_houdini-17.5.173/htoa-3.3.0_rf4b10e6_houdini-${HOUDINI_VERSION}/scripts/bin;;C:/ProgramData/Redshift/bin"

With just 02 lines you get HtoA, redshift, GameDevToolset
You get the idea for the rest

What @rachid Hadj Abderrahmane posted is right, but I always put HtoA last in PATH so I changed it to this:

PATH = "$PATH;C:/ProgramData/Redshift/bin;C:/Users/Steven/htoa/htoa-3.3.0_rf4b10e6_houdini-17.5.173/htoa-3.3.0_rf4b10e6_houdini-${HOUDINI_VERSION}/scripts/bin"

If you still have problems, start with the simplest houdini.env possible:

# htoa config start
PATH = "$PATH;D:/solidangle/htoa/htoa-3.3.0_rf4b10e6_houdini-17.0.416/htoa-3.3.0_rf4b10e6_houdini-${HOUDINI_VERSION}/scripts/bin"
HOUDINI_PATH = "D:/solidangle/htoa/htoa-3.3.0_rf4b10e6_houdini-17.0.416/htoa-3.3.0_rf4b10e6_houdini-${HOUDINI_VERSION};&"
# htoa config end

Make sure that works. Then start adding the other plugins, one at a time.

[sfshook22]

Stephen,

I commented out all other plugins for testing purposes when ever I upgrade or add functionality to the env file.

I upgraded to 4.0.0 yesterday to see if that would help and it didn't as I still have the same problem.

I have standard installation of Houdini and Arnold and the Houdini.env is:

# htoa config start

PATH = "$PATH;C:/Users/Steven/htoa/htoa-4.0.0_r33d20a4_houdini-17.5.173/htoa-4.0.0_r33d20a4_houdini-${HOUDINI_VERSION}/scripts/bin"

HOUDINI_PATH = "C:/Users/Steven/htoa/htoa-4.0.0_r33d20a4_houdini-17.5.173/htoa-4.0.0_r33d20a4_houdini-${HOUDINI_VERSION};&"

# htoa config end

Thank you for taking the time to look into this,

Steve

[Stephen.Blair]

@Steven Shook Ok, that is how it should be.

You still have the same problem with the render view, but now you also don't see any of the Arnold shaders, right?

The missing shaders is a problem with the environment.

Can you post your Houdini_Info (in Houdini, click Help > About > Show Details) ?

Still can't render to the render view in fact can't do anything. I don't see most of the shader nodes.
