I am planning on doing a projection mapping onto a marquee this Halloween. This will be with the intention of transforming it into an interactive visual of a witches house. The projector handles the sizing fine (roughly a 6x2m area). What I need is a relatively inexpensive material that would handle the wind/rain/sun (delete where applicable) on the day/night. I was looking at a white Tarp, cheap and robust but have seen mixed reviews about how well this works overall. Does anyone on here have any experience of this? I see some people have used it for outdoor cinema screens online, but a first hand account would be appreciated.

Many thanks in advance :)

So is this mapping and your looking to cover the surface with a white material, or your needing a large screen to project your images on? The one issue with a white plastic tarp is reflection. Tarps are usually pretty shiny, and the light reflection could hurt the illusion a little.

That is what I thought but some people were swearing by it, I thought it might refelect too much and hot spot.

It is to cover one side of the marquee but that would basically be a 2x6m screen.

Is it a theater marquee that is backlight and already white? If so you could turn off the backlight and just project directly onto it. If you don't have the option of turning off the backlight, then a tarp or canvas may be your only option. I know I'm not the only mapper/projection user on here. The more info you can provide as to what your working with, maybe even a picture or two, would help us help you better.

I can see the English and American meanings have been at force here, apologies :)

The above is what I mean about marquee and I basically want to map onto one side. Unfortunately my side panels have large windows so no chance of projecting onto it. I aim to make one side give an effect of an old cabin and potentially the roof also (depending how much ambient light falls on it and if it is visible without).

Ahhhh. Now it takes on a whole new meaning. You could hang standard white bedsheets from the poles on the inside to cover the windows. You could also use the Windows as part of the cabin. Although, that option wouldn't leave a lot of surface that's usable. I'm assuming this will be front projected and not rear projected from the inside.

I want to create windows as part of the mapping as I want the effect of movement and depth within the cabin. Unfortunately this will glare off the windows too much as that is a shiny thick plastic and too much creasing as opposed to glass. Want to wrap around this one side. This is a concept drawn up which probably will help you visualise it further.

Thank you for your help thus far :)

Thank you for your help so thus far :)
If you already have your room set up, I would test the reflective properties of it. It is pretty much made of white tarp, so it would let you know if a tarp to cover the one side is workable. Making sure the surface is pulled taught to avoid wrinkles and wind movement will be critical, as either hurts the illusion too. You may have to deal with what little reflection you get from a tarp. Distance of the projector from the projected surface will also control how much reflected light you get. I don't know if I got you any closer to an actual answer now. Haha. I project onto the surface on my home, and only have minor reflection from the windows, all of which is directed towards the sky due to the angle of projection.

I'll grab out on of the wall panels and test it out, probably the best bet.

Thank you for your help. I had a look through projections you have done and they look very good :)

Thanks for all your help
