Hi There,
I'm hvaing trouble getting a background to be visible in a vue render from Microstation. Anyone got any ideas where I'm going wrong?
The view dialog box with a vessel rendered, but showing a black background.
The Atmosphere editor dialog box, on the Environment Map tab, with Environment Map ticked and a image selected and a Mapping mode of Cylindrical.
The vue render dialog is pointing to the Atmosphere preset of 'Myles' which has the Environment Map set as above. To my understanding the sky background should be rendered?
What am I doing wrong??
Cheers,
Myles.
Hi,
Are you using an orthographic or camera view ? you need a camera view to see the environment. Also I would increase the intensity and exposure values, they look too low.

Hi Paul,
Thanks for the response.
Camera defined as a three point.
Intensity and exposure values increased.
vue render dialog still produces a blank background - although it is slightly lighter than the previous, so I guess increasing the intensity and exposure has done something.
The image used for the environment map is a jpg, located on a server [as are all other textures and materials, and even the design file itself.]
I have also tried an image located on the local HDD which made no difference.
Hi Myles,
try to set Intensity between 30/50.

Hi Diego,
Thanks for your suggestion.
My sliders for exposure and intensity go from -1.00 to +1.00.
I've tried a render with intensity set to +0.40, however this still has a black background, not the image set in the Environment Map tab of the Atmosphere Editor.
mine's too but it's a fake limit. Try typing in
Ah, ok then!
I entered 40 in, this time during the rendering process the background appeared when the image was rendering/ calculating the 'squares' of the image. But once this was complete and the finished image was displayed on screen, the background image dissapeared and was replaced by the black background.
it also looks like the background image is rotate 90 degrees but that'll be simple to sort out. Although as the material jp image is a panoramic image in landscape I find it odd it is automatically set 90 degrees off [anyway this is a different issue - more an observation, and is not important right now]
have you tried to use an HDRI set to Spherical?
Thanks, I appreciate your time and suggestions.
I've tried with a .hdr file, it seems to do the same as the jpg. The render process where it blocks the image in shows a background image, bit when the process finished the vue render loses the background as shows just black.
Are there any other ways to get a background in using the vue renderer?
I've had a play with a different method to render the image. Using the Record script button
pointing all the options on the record script dialog box to the same settings used for the single shot vue renderer
the resulting image is rendered correctly with the background showing
The image used as the background id a .hdr file
Is there away to scale the background image? I have seen options to rotate the background.
I cant really tell which portion of the background hdr is shown in the rendered image. How would I go about getting the background hdr moved around to show the sun behind the vessel? other than randonly rotating the background hdr - rendering an image, then repeating this process? is there a way to do this 'interactivley'?
You can use a vue atmosphere which has an environment map as a background in a display style. you can then use the sliders on the environment option button to shift the image in the microstation view, this will then update the atmosphere settings for the render.. You can then choose "None" as your atmosphere so it picks up the display style including the rotation & offset.
So display style dialog.
Atmosphere dialog.
Microstation view
Render dialog
