Octane plugin does not install in LW-11.5 or 11.6 Tweet

[juanjgon]

This is the x32 Octane build for the last 11.6 pre-release, LW build 2708 ... please try this x32 version with your system, you only need to repleace the plugin file you have with this new x32 one (you can rename it if you want to overwrite your LWOctane_x32.p file and simple start LW again)

As you know 11.6 is in beta stage, and there are changes in each build that breaks the Octane plugin, so perhaps for the next LW11.6 release or for the final 11.6 I am going to need to update the plugin again.

LW 11.6 x32 Octane plugin is now able to be enabled, Thank You.
Besides having LW 11.6 x64, I also have LW 11.5.1 x64 installed and the Octane plugin does not installed on it either.

[juanjgon]

OK ... we have something ... at least you can use Octane with the LW x32 version.

Perhaps like you say before we have a problem with the redistributable. It installs in your system the "vcomp100.dll" file.

You can try to search this file in your HD to see how many copies of this file are installed, perhaps a driver or other system component installed a wrong version of this file ...

Here is the results of my vcomp100.dll search. It seems that Octane Render standalone installed the vcomp100.dll also.

[juanjgon]

I think that your vcomp100.dll files are OK. Plugin uses the system vcomp100, while Octane Standalone uses it's own dll.

Can you please try the installation steps I post some days ago?

Uninstall the x64 redistributable and delete the Octane.dll and Octane.dat from your LW/bin

(a) Try to add the plugin without redistributable and without Octane.dll and Octane.dat
(b) Try to add the plugin after add the Octane.dll and Octane.dat to your LW/bin (but without the redistributable)
(c) Delete again the Octane.dll and Octane.dat from your LW/bin, Install the redistributable and try to add the plugin
(d) Finally try to add the plugin with both redistributable installed and the Octane.dll and Octane.dat in your LW/bin

The goal is to see if at some point we get a windows error window about a missing .dll

Test(A)results: Windows error, "missing Ocatane.dll". As LW is trying to load it self. When I close the error box, LW finishes loading.

Test(B)results: LW error, "cannot load external plugin file"

Test(C)results: Windows error, "missing Ocatane.dll". As LW is trying to load it self. When I close the error box, LW finishes loading. Then when trying to add plugin I get the Windows error again "missing Ocatane.dll". When I close the error box. I get a LW error "cannot load external plugin file".

Test(C)results: LW error, "cannot load external plugin file"

Thanks ... from (b) I think that the problem is the vcomp100.dll. But ... what could be the problem?

In the (b) steep you should get a Windows error window with the missing vcomp100.dll message. There are two possibilities: there is other vcomp100.dll in your system that is not compatible with the VC++ SP1 I use for development, or plugin doesn't try to load this .dll at all and simple fail to install.

Let me think about it. I am sure the that there is a solution, and perhaps it is really easy, but I need to find it

Ok ... I am sure that problem are the redistributable files. Please, make this test:

- Uninstall your Visual C++ SP1 x64 redistributable
- Download the attached .rar file
- Put the two .dll files available inside this .rar file inside your Lightwave(x64)/bin directory (this files are the libs needed by the plugin to load)
- Try to add the plugin again (of course the x64 plugin, and be sure that you have also the Octane.dll and Octane.dat x64 files in your Lightwave(x64)/bin directory)

The goal is to force the plugin to use always the valid msvcr100.dll and vcomp100.dll ... the first place where plugin is going to search them is always the directory of the application.

I can reproduce your problem if the plugin read this files from the system directory and they are older than the SP1 needed by my compiler.

You did it! Everything is working just fine in LW 11.5 and 11.6..
Thank you for your hard work in finding the solution and sticking with me to the end.
Take Care Juanjo

Great, finally plugin works in your system

I think that the problem is that something in your computers (perhaps a driver, or a system utility) puts an older version of the redistributable files in a folder that has priority over the standard folder for this .DLL files, and plugin load the wrong files. If you put the redistributable files inside the LW/bin folder, we are sure that plugin is going to load the correct .DLLs

Anyway no other user reported this problem before, so as I say before this issue could be something related to a driver or utility that is only available in your computer.
