Hi,

I use the following code, it display 'rayType', the printed value is always RAYTYPE_DIFFUSE. 

        printf("%d\n", nextEventPath.rayType);

        if (nextEventPath.rayType == RAYTYPE_DIFFUSE) {....}

Like this the application DOES NOT ENTER into the IF !

If I do this :

        printf("%d\n", nextEventPath.rayType);

        nextEventPath.rayType = RAYTYPE_DIFFUSE;

        if (nextEventPath.rayType == RAYTYPE_DIFFUSE) {....}

It works !

So, I don't know why, it 'print' that the value is DISPLAY_VALUE but it sounds that there is a problem with the IF.

I work on the CPU !

What happens if the printf is set to print some other variable?

Can you check if it is a problem with printf or with if condition. Does tha same happen if you remove printf statement.

You've got to try to place the printf() inside the if { ... } block, results are interesting with all SDK versions, including 2.4, hehe :)

I think I reported that a while ago but it's not fixed in 2.4...
